Adjuvant combined paclitaxel and carboplatin chemotherapy for glassy cell carcinoma of the uterine cervix: report of three cases with clinicopathological analysis

Glassy cell carcinoma of the uterine cervix (GCC) is a rare form of cervical carcinoma that is characterized by aggressiveness and poor prognosis. We reviewed a variety of clinicopathological features, treatment strategies, and outcomes in three women with GCC. The three patients were successfully treated by radical hysterectomy with pelvic/para-aortic lymphadenectomy. The patients had stage Ib1, stage IIa, and stage Ib2 tumors without lymph node metastases. A 44-year-old woman with stage Ib1 tumor did not undergo adjuvant chemotherapy or radiation therapy. She had recurrent pelvic tumors 12 months after surgery, and died 6 months after the recurrent disease. The histological findings of her cervix, which were different from the other two patients, did not show the marked infiltration of eosinophils. The other two patients with stage Ib2 and IIa tumors underwent adjuvant chemotherapy with paclitaxel and carboplatin, and had disease-free survival for 4.5 and 9 years. We think that all patients with GCC of stage Ib1 or more should undergo adjuvant chemotherapy of paclitaxel and carboplatin or other adjuvant therapies.     

A comparison of prognoses of FIGO stage IB adenocarcinoma and squamous cell carcinoma

OBJECTIVES: The objective of this study was to compare clinical and pathologic variables and prognosis of FIGO stage IB adenocarcinoma and squamous cell carcinoma of uterine cervix. METHODS: A retrospective review was performed of 521 patients with stage IB squamous cell carcinoma and adenocarcinoma of cervix who treated primarily by type 3 hysterectomy and pelvic and/or para-aortic lymphadenectomy at Hacettepe University Hospitals between 1980 and 1997. RESULTS: Age, tumor size, grade, depth of invasion, lymph node metastasis, parametrial, vaginal, and lymphvascular space involvement (LVSI) were not different between two cell types except number of the lymph nodes involved. Metastasis to three or more lymph nodes was significantly higher in adenocarcinoma. Overall and disease-free survival were 87.7%, 84.0% versus 86.4%, 83.1% for squamous cell carcinoma and adenocarcinoma, respectively (P > 0.05). The rate and site of recurrence were not different between two cell types. Multivariate analysis of disease-free and overall survival revealed independent prognostic factors as tumor size, LVSI, number of involved lymph node, and vaginal involvement. CONCLUSION: Prognosis of FIGO stage IB cervical cancer patients who were treated by primarily radical surgery was found to be same for those with adenocarcinoma and squamous cell carcinoma.     

Multivariate analysis of the prognostic factors and outcomes in early cervical cancer patients undergoing radical hysterectomy

OBJECTIVE: This study was performed to identify pathologic and clinical risk factors that best predicted 5-year recurrence-free survival (RFS) among patients with early-stage cervical carcinoma, treated by radical hysterectomy and pelvic lymphadenectomy. METHODS: The records of 197 patients with early-stage invasive cervical carcinoma who underwent radical hysterectomy and pelvic lymphadenectomy from 1990 to 1999 were retrospectively reviewed. Clinical and pathologic variables including age, tumor size (TS), clinical stage, depth of invasion (DI), lymphovascular space involvement (LVSI), cell type, tumor grade, lymph node metastases (LNM), parametrial invasion, surgical margin involvement, and pattern of adjuvant therapy were analyzed using univariate and multivariate methods to define those variables that best predicted RFS. RESULTS: Outer 1/3 invasion, LVSI, and LNM were identified as independent poor prognostic factors, which were used to define three prognostic groups: patients (n = 104) with good prognoses (LVSI (-) and LNM (-)), patients (n = 46) with intermediate prognoses (either LVSI (+) without outer 1/3 invasion or LNM (+) without LVSI), and patients (n = 47) with poor prognoses (LVSI (+) patients with outer 1/3 invasion). The estimated 3-year RFS for patients with LVSI and deeply invasive tumors regardless of nodal status and/or nodal metastases receiving adjuvant CT + RT was significantly greater than that for patients who received only adjuvant radiotherapy (80% vs. 49%, P = 0.048 in the group of patients with LVSI and deeply invasive tumors with positive nodes and without positive nodes; 87% vs. 36%, P = 0.013 in the group of patients with LVSI and deeply invasive tumors with positive nodes only). CONCLUSIONS: The multivariate analysis and prognostic grouping system maximally separated patients with early-stage invasive cervical carcinoma into groups with good, intermediate, or poor prognoses, with 3-year RFSs of 90%, 82%, 67%; and 5-year RFSs of 89%, 69%, 43%, respectively. CT + RT played a role in improving RFS among patients with LVSI and deeply invasive tumors and poor prognoses.     

Surgical-pathological predictors of disease-free survival and risk groupings for IB2 cervical cancer: do the traditional models still apply?

OBJECTIVE: To evaluate how the independent predictors of recurrence for stage IB2 cervical cancers treated with up-front radical hysterectomy apply to established risk models. METHODS: Patients with IB2 cervical cancers diagnosed from 1990 to 2000 were identified from tumor registries of two institutions. Patients were classified into risk groups: high-risk (HR) (positive nodes, parametria, or margins), intermediate-risk (IR) (positive lymph vascular space involvement (LVSI) with any cervical stromal invasion (CSI), or (-) LVSI and > middle- CSI), or low-risk (LR) (absence of HR or IR characteristics). Disease-free survival (DFS) was estimated by Kaplan-Meier method and comparisons between subgroups were studied by log rank. A Cox proportional hazards model was used to determine independent predictors of recurrence. RESULTS: We identified 86 patients with stage IB2 tumors treated by RH. We found 34% of patients to be HR, 60% IR, and 6% LR. Of the 52 IR patients, 28 had (+) LVSI with superficial, middle, and outer 1/3 CSI, and 24 had (-) LVSI with middle or outer 1/3 invasion. Overall, postoperative adjuvant radiation (PRT) was used in 52% of the 86 patients, including 0/5 LR, 16/52 IR, and 29/29 HR patients. Univariate predictors of recurrence were pelvic nodal disease, (+) LVSI, (+) parametria, outer 1/3 CSI, and tumor size > 6 cm. Age, grade, histology, and the use of postoperative radiation were not associated with recurrence. Multivariate analysis identified LVSI as the only independent predictor of recurrence (RR 5.2, P = 0.03). Two-year DFS for LR, IR, and HR patients was 100%, 83%, and 60%, respectively. Only 4/24 (17%) IR patients with (-) LVSI got PRT compared with 12/28 (43%) of IR patients with (+) LVSI. The 2-year DFS for IR patients with (-) LVSI was 96%. IR (+) patients recurred more frequently with a 2-year DFS of 71%. CONCLUSIONS: Overall, 66% of patients with IB2 disease were classified as having low or intermediate-risk disease. IR patients with (-) LVSI and all LR patients did well with surgery alone. This study defines the independent importance of LVSI and questions the utility of published IR models when applied to stage IB2 cervical cancer.     

Prognostic factors of adenocarcinoma of the uterine cervix

OBJECTIVE: The prognostic importance of adenocarcinoma of the uterine cervix was investigated. Methods. One hundred ninety-three patients (144 had stage I disease, 41 stage II, and 8 stage III-IV) with invasive adenocarcinoma of the uterine cervix treated initially at the Aichi Cancer Center between 1964 and 1995 were studied. RESULTS: Of all the invasive cervical cancers, 8.8% were adenocarcinomas that had been increasing during the past decade. The overall 5-year survival for stage I was 88.8%, stage II 44.9%, and stage III-IV 0% In univariate analysis, the clinicopathological factors associated with overall survival and disease-free survival were age of patient, stage of disease, presence of nodal metastasis, number of lymph nodes involved, lymph-vascular space invasion, tumor size, and intraperitoneal metastasis. Multivariate analysis performed in all cases identified the clinical stage of disease, the presence of nodal metastasis, number of lymph nodes involved, lymph-vascular space invasion, and tumor size as the independent risk factors for recurrence and survival. In the analysis of stage I disease, lymph node metastasis and tumor size were the significant prognostic factors, while lymph-vascular space invasion and tumor size were the factors in advanced disease. Tumor grade and histological type were not associated with recurrence and survival. CONCLUSION: These results suggested the association of lymph node metastasis with the prognosis of early stage adenocarcinoma of the uterine cervix and lymph-vascular space invasion with the advanced stage. Tumor size was an independent risk factor throughout all stages.     

Prognostic factors affecting disease-free survival in early-stage cervical cancer patients undergoing radical hysterectomy and pelvic-paraaortic lymphadenectomy

OBJECTIVE: This study was performed to identfy surgical and histopathologic prognostic factors that could predict 5-year disease-free survival (DFS) after patients underwent radical hysterectomy and pelvic-paraaortic lymphadenectomy for FIGO Stage I-II cervical carcinoma. METHODS: A retrospective review was performed for all patients undergoing primary radical hysterectomy and pelvic-paraaortic lymphadenectomy for Stage I-II cervical cancer at Ankara Oncology Hospital from 1995 to 2000. Clinical and pathologic variables including age, tumor size (TS), clinical stage, depth of invasion (DI), lymphovascular space involvement (LVSI), cell type, tumor grade, lymph node metastases (LNM), parametrial involvement, surgical margin involvement and pattern of adjuvant therapy were analyzed using univariate analyses. DFS was performed by the Kaplan-Meier method and the log-rank test. Independent prognostic and predictive factors affecting DFS were assessed by the Cox proportional hazard method. RESULTS: Ninety-three patients underwent primary type III radical hysterectomy and pelvic-paraaortic lymphadenectomy. Five-year DFS was 87.1%. LVSI, parametrial involvement and grade were the prognostic factors that independently affected survival. DFS was not significantly different for age, disease status of the surgical margins, tumor size, depth of invasion, cell type, pelvic lymph node metastases and adjuvant radiotherapy. CONCLUSIONS: LVSI, parametrial invasion and histologic grade 2-3 were independent prognostic factors in early-stage cervical cancer patients. Adjuvant radiotherapy in these patients provides no survival advantage.     

Does the density of lymphatic vascular space invasion affect the prognosis of stage Ib and IIA node negative carcinoma of the cervix?

Abstract. Sykes P, Allen D, Cohen C, Scurry J. & Yeo D. Does the density of lymphatic vascular space invasion affect the prognosis of stage Ib and IIA node negative carcinoma of the cervix? Int J Gynecol Cancer 2003; 13: 313–316.
Lymphatic vascular space invasion (LVSI) has been noted as a poor prognostic factor in many tumors. In some studies of carcinoma of the cervix, LVSI has been demonstrated to be independent of other prognostic factors. The aim of this study is to evaluate if, by a simple quantitative technique, the density of lymphatic invasion could be correlated with the risk of recurrence in node negative early stage carcinoma of the cervix. We analyzed the pathology and clinical course of 71 consecutive patients with stage IB and IIA carcinoma of the cervix treated primarily by radical hysterectomy and pelvic lymphadenectomy. All cases had negative nodes and adequate surgical margins. There were 67 patients suitable for evaluation. Tumour type, grade, stage and the dimensions of the tumor were recorded. The density of LVSI was categorized as absent (45%), mild (15%), moderate (33%) or severe (7%) depending on the number of lymphatic vascular spaces involved per high power field in the worst affected slide. The patients were followed for 2–8½ years with a mean follow up of 4 years and 2 months. There were 13 recurrences and 7 deaths. All recurrences occurred in less than 2 years after surgery. The risk of recurrence was 40% for patients with extensive LVSI, 32% for moderate, 30% for mild and 3% if LVSI was absent. Only the presence of LVSI was associated with an increased risk of recurrence. The density of lymphatic invasion as represented by the number of lymphatic spaces occupied on the worst histological slide offered no further clinically useful information.     

Adjuvant chemotherapy as treatment of high-risk stage I and II endometrial cancer

OBJECTIVE: This study was performed to define the subgroups of patients who benefit from postoperative adjuvant chemotherapy in stage I and II endometrial carcinoma. METHODS: A retrospective review of 170 International Federation of Gynecology and Obstetrics (FIGO) stage I and II endometrial carcinoma patients treated between 1988 and 2000 at Niigata University Hospital was performed. All patients underwent surgery, of which 41 patients underwent adjuvant chemotherapy, consisting of intravenous cisplatin, doxorubicin, and cyclophosphamide. Multivariate analysis was performed for the prognostic factors and actuarial techniques were used for the survival and recurrence rates. RESULTS: The patients were divided into low-risk and high-risk groups based on the number of prognostic factors (tumor grade G3, outer half myometrial invasion, lymph-vascular space involvement (LVSI), and cervical invasion). The 5-year disease-free survival and the 5-year overall survival for the low-risk group were 97.4%, and 100%, respectively, which were significantly better than 77.4% and 88.1% for the high-risk group (P < 0.0001, P < 0.0001), respectively. Among high-risk group patients, the 5-year disease-free survival and the 5-year overall survival were 88.5% and 95.2% in 26 patients treated with adjuvant chemotherapy, and 50.0% and 62.5% in eight cases who underwent only surgery (P = 0.0150, P = 0.0226). Disease recurrence occurred in 7 (20.6%) of 34 high-risk group patients. Four of seven recurrences occurred in patients who did not receive postoperative chemotherapy, in which all four were distant failure. In the remaining three patients who were in the CAP group, two had vaginal wall recurrence and only one had pulmonary recurrence. Three recurrences were also observed in the 133 low-risk group patients. Only isolated vaginal wall recurrence occurred in three patients without adjuvant chemotherapy after the initial surgery. CONCLUSIONS: There is possibility that postoperative adjuvant CAP may be omitted in surgical stage I or II endometrial cancer patients with 0 or 1 prognostic factor. The high-risk group of patients should be treated with postoperative adjuvant CAP to decrease distant failure and improve prognosis.     

Lymph node metastasis in endometrioid adenocarcinomas of the uterine corpus with occult cervical involvement

Objective

Surgical-pathologic studies have defined the risk of lymphatic metastasis in clinical stage I endometrial cancers. However, data on the risk of lymph node metastasis in endometrial cancers involving the uterine cervix are less robust. The aim of this study was to determine the risk of lymphatic metastasis in patients with endometrial cancers with occult tumor extension to the uterine cervix.

Methods

Our institutional tumor registry identified all patients with endometrioid endometrial cancers who underwent comprehensive surgical staging. Patients with gross involvement of the cervix and patients with extra-uterine disease were excluded. The risk of lymphatic metastasis associated with cervical involvement was analyzed in the context of known uterine risk factors for lymphatic metastasis such as age, depth of invasion, grade, and lymphovascular space invasion (LVSI).

Results

We identified 169 patients who met inclusion and exclusion criteria. Univariate analyses revealed that LVSI (p < 0.01), tumor grade (p < 0.01), depth of myometrial invasion (p < 0.01), tumor free distance (p < 0.01), tumor size (p = 0.02), and cervical involvement (p < 0.01) were associated with lymphatic metastasis while age at diagnosis (p = 0.85) was not. Multivariate analyses revealed that only LVSI (p < 0.01), tumor grade (p = 0.02), and depth of myometrial invasion (p = 0.03) were independently associated with lymphatic metastasis.

Conclusion

Cervical involvement is not an independent predictor of lymphatic metastasis in endometrial cancer. In an unstaged patient, decisions regarding adjuvant treatment or additional diagnostic procedures such as lymphadenectomy should be based on uterine factors.     

Outcomes of Minimally Invasive versus Open Radical Hysterectomy for Early Stage Cervical Cancer Incorporating 2018 FIGO Staging

Study ObjectiveTo compare outcomes after minimally invasive surgery (MIS) vs open radical hysterectomy for early stage cervical cancer incorporating 2018 Federation of Gynecology and Obstetrics (FIGO) staging.DesignA retrospective analysis.SettingA single teaching hospital.PatientsPatients after radical hysterectomy for stage IA1 with lymphovascular invasion, IA2, or IB1 squamous, adenosquamous, or adenocarcinoma of the cervix between 2007 and 2018, mirroring the Laparoscopic Approach to Cervical Cancer trial criteria.InterventionsThe use of MIS surgery for performing radical hysterectomy.Measurements and Main ResultsThe outcomes were compared between patients undergoing MIS vs open approaches. A total of 126 patients met the inclusion criteria. The approach was open in 44 patients (35%) and MIS in 82 patients (65%); 49% were laparoscopic and 51% were robotic. Distribution based on the 2009 FIGO staging showed 1 stage IA1 with lymphovascular invasion, 15 stage IA2, and 110 stage IB1 patients. Although not statistically significant, the 3-year disease-free survival (DFS) was higher in the open compared to the MIS group (95% vs 87%; p = .17), and the overall survival was higher in the open compared to the MIS group (97% vs 92%; p = .25).Fourteen patients whose disease recurred were Stage IB1 by FIGO 2009 staging; 11/14 were reclassified to a higher stage by 2018 FIGO staging (5/5 open, 6/9 MIS). Adjuvant therapy was recommended for all these patients based on the Sedlis criteria (10/14) or other risk factors (4/14). Despite this, only 1/9 of MIS patients whose disease recurred received adjuvant therapy compared with 3/5 patients whose disease recurred in the open group (p = .05).ConclusionIn a cohort of patients similar to that of the Laparoscopic Approach to Cervical Cancer trial, 2018 FIGO staging may be useful to refine indications for MIS radical hysterectomy in early stage cervical cancer. However, disparate outcomes between MIS and open approaches may be explained by differences in compliance with National Comprehensive Cancer Network guidelines for adjuvant therapy.     

Association between CD31 expression and histopathologic features in stage IB squamous cell carcinoma of the cervix

This study was undertaken to evaluate the association between the expression of CD31 in the tumor and the histopathologic findings in patients with carcinoma of the cervix. This study included prospectively 30 women, aged 46.6 +/- 10.7 years, with stage IB squamous cell carcinoma of the cervix submitted to radical hysterectomy from November 2001 to September 2002. Samples from the tumor were taken and immunohistochemically evaluated by a monoclonal antibody for CD31. Clinicopathologic characteristics such as stage, tumor size, grade of differentiation, lymphatic vascular space invasion (LVSI), parametrial involvement, and status of pelvic lymph nodes were also recorded. The clinical stage (FIGO) was IB1 in 22 patients (73.3%) and IB2 in 8 patients (26.7%). The expression of CD31 was significantly associated with tumor size and the presence of LVSI, but not with grade of differentiation and vaginal or parametrial involvement (P= 0.03, P= 0.032, P= 0.352, P= 0.208, and P= 0.242, respectively). On univariate analysis, the presence of pelvic lymph node metastasis was influenced by LVSI (P= 0.003) and CD31 expression (P= 0.032). However, on multivariate analysis, the presence of LVSI (P= 0.007) was the only independent predictor of pelvic lymph node metastasis. The CD31 expression in tumor is significantly associated with LVSI and tumor size in patients with early-stage squamous cell carcinoma of the cervix.     

Should the presence of lymphvascular space involvement be used to assign patients to adjuvant therapy following hysterectomy for unstaged endometrial cancer?

Objective. Thegoal of this study was to determine the influence of LVSI (lymphvascular space involvement) on the risk of lymph node metastases from endometrial cancer.Methods. All patients with surgically staged endometrial cancer from 1998 to 2000 were identified from divisional databases. The influence of LVSI on the risk for nodal metastases was determined after controlling for tumor grade and depth of invasion, and comparisons were made with the chi(2) or Fisher's exact tests. Multivariable analysis was performed using a logistic regression model.Results. We identified 366 patients who fit the study criteria. Pathologically, 92/366 (25%) tumors had LVSI, and 46 patients (13%) had evidence of pelvic lymph node metastases. Cancers with LVSI were significantly more likely to have nodal disease (35/92 versus 11/274, P < 0.001). When controlled for tumor grade, the presence of LVSI led to an increased incidence of pelvic node metastases (P < 0.001 for all grades). When stratified by depth of invasion in thirds, the presence of LVSI led to a significantly increased chance of pelvic lymph node metastases (P < 0.05 for each strata). When tumor grade and depth of invasion were evaluated together, LVSI led to a significantly increased risk of pelvic node metastases in patients with deeply invasive tumors. In a multivariable analysis, LVSI led to a significantly increased risk for pelvic lymph node metastases (P < 0.05).Conclusion. LVSI leads to an independent and significantly increased risk for pelvic lymph node metastases. As such, the presence of LVSI may indicate the need for lymphadenectomy or adjuvant therapy for potential regional lymph node metastases in patients with unstaged endometrial cancer.     

Prognostic factors in FIGO stage IB cervical cancer without lymph node metastasis and the role of adjuvant radiotherapy after radical hysterectomy

OBJECTIVES: The aim of this study was to evaluate the clinical and pathologic prognostic variables for disease free survival, overall survival and the role of adjuvant radiotherapy in FIGO stage IB cervical carcinoma without lymph node metastasis. METHODS: A retrospective review was performed of 393 patients with lymph node negative stage IB cervical cancer treated by type 3 hysterectomy and pelvic lymphadenectomy at the Hacettepe University Hospitals between 1980 and 1997. RESULTS: The disease free survival and overall survival were 87.6 and 91.0%, respectively. In univariate analysis, tumor size, depth of invasion, vaginal involvement, lympho-vascular space involvement (LVSI) and adjuvant radiotherapy were found significant in disease free survival. Overall survival was affected by tumor size, LVSI, vaginal involvement and adjuvant radiotherapy. Tumor size, LVSI and vaginal involvement were found as independent prognostic factors for overall and disease free survival in multivariate analysis. Disease free survival, recurrence rate and site did not differ between patients underwent radical surgery and radical surgery plus radiotherapy. CONCLUSION: Tumor size, LVSI and vaginal involvement were independent prognostic factors in lymph node negative FIGO stage IB cervical cancer. Adjuvant radiotherapy in stage IB cervical cancer patients with negative nodes provides no survival advantage or better local tumoral control.     

Histopathological prognostic factors of adult granulosa cell tumors of the ovary.

BACKGROUND: The prognostic factors of adult granulosa cell tumor (AGCT) have not been well defined. METHODS: In 27 AGCT patients, we examined clinical stage, microscopic patterns, mitotic index (MI), and lymph-vascular space invasion (LVSI) to determine whether these factors were related to disease-free survival (DFS) of patients with AGCT. We also performed immunohistochemical examination for p53. RESULTS: Seventeen cases represented stage I tumors, four stage II, five stage III, and one stage IV. Patients with stage I disease had more favorable prognosis than those with stage II to IV disease (p=0.034). There was no relation between the microscopic patterns and the DFS. The MI, which was categorized into < or =3/10 high power field (HPF) and > or =4/10 HPF, was significantly related to patients DFS (p<0.0005). The DFS time for patients with moderate or prominent LVSI was significantly shorter than that for patients with no or minimal LVSI (p<0.0001). By multivariate analysis, MI and LVSI were shown to be independent prognostic factors. Five of seven patients with recurrent tumor had extrapelvic spread; two in the abdominal cavity and three in the liver. CONCLUSION: The results of this study suggest that prognosis for patients with AGCT depends on the MI and LVSI. During the follow-up period of patients, they need to be examined for distant metastasis including liver.     

Multivariate analysis of histopathologic prognostic factors for invasive cervical cancer treated with radical hysterectomy and systematic retroperitoneal lymphadenectomy

BACKGROUND: The aim of this study was to identify the independent histopathologic prognostic factors for patients with cervical carcinoma treated with radical hysterectomy including paraaortic lymphadenectomy. METHODS: A total of 187 patients with stage IB to IIB cervical carcinomas treated with radical hysterectomy and systematic retroperitoneal lymphadenectomy were retrospectively analyzed. The median follow-up period was 83 months. Cox regression analysis was used to select independent prognostic factors. RESULTS: Using multivariate Cox regression analysis, lymph node (LN) status (negative vs. metastasis to pelvic nodes except for common iliac nodes vs. common iliac/paraaortic node metastasis), histopathologic parametrial invasion, lymph-vascular space invasion (LVSI), and histology of pure adenocarcinoma were found to be independently related to patients' poor survival. For patients who had a tumor histologically confined to the uterus and have neither parametrial invasion nor lymph node metastasis, LVSI was the most important prognostic factor, and histologic type, depth of cervical stromal invasion, and tumor size were not related to survival. The survival of patients with a tumor extending to parametrium or pelvic lymph node(s) was adversely affected by histology of pure adenocarcinoma. When the tumor extended to common iliac or paraaortic nodes, patients' survival became quite poor irrespective of LVSI or histologic type of pure adenocarcinoma. Patients' prognosis could be stratified into low risk (patients with a tumor confined to the uterus not associated with LVSI: n = 80), intermediate risk (patients with a tumor confined to the uterus associated with positive LVSI, and patients with squamous/adenosquamous carcinoma associated with pelvic lymph node metastasis or parametrial invasion: n = 86), and high risk (patients with pure adenocarcinoma associated with pelvic lymph node metastasis or parametrial invasion, and patients with common iliac/paraaortic node metastasis: n = 21) with an estimated 5-year survival rate of 100 +/- 0 (mean +/- SE)%, 85.5 +/- 3.9%, and 25.1 +/- 9.7%, respectively. CONCLUSIONS: LN status, parametrial invasion, LVSI, and histology of pure adenocarcinoma are important histopathologic prognostic factors of cervical carcinoma treated with radical hysterectomy and systematic retroperitoneal lymphadenectomy. Prognosis for patients with cervical carcinoma may be stratified by combined analysis of these histopathologic prognostic factors. Postoperative therapy needs to be individualized according to these prognostic factors and validated for its efficacy using randomized clinical trials.     

Factors predicting recurrence in patients with stage IA endometrioid endometrial cancer: what is the importance of LVSI?

The aim of this study is to define the clinical and pathological prognostic factors for recurrence and to evaluate the recurrence patterns and adjuvant therapies used in this group of patients with stage IA endometrioid type endometrial cancer (FIGO 2009—International Federation of Gynecology and Obstetrics). Among the patients with epithelial endometrial cancer operated between January 1993 and May 2013 in a single institution, 720 patients with stage IA endometrioid endometrial cancer were included. Patients with a tumor type of serous, clear cell, mucinous, undifferentiated, and mixed type and with a tumor containing sarcomatous component and the patients with a secondary primer cancer were excluded from the study. Lympho-vascular space invasion (LVSI) was present in 60 (8.3%) patients. Pelvic and para-aortic lymphadenectomy was performed in 266 (36.9%) patients. Median follow-up time was 48 months (range 3–240). Recurrence occurred in 23 (3.4%) patients and 6 (0.9%) died of disease. The median time-to recurrence (TTR) was 24 months (range 4–52 months) in the patients with recurrence. LVSI was associated with recurrence in the univariate analysis. Five-year disease-free survival (DFS) decreased from 96.8 to 80.1% in the presence of LVSI (p < 0.001). This association could not be shown in patients who had had lymphadenectomy (p = 0.136). Extra-pelvic recurrence occurred in 6.7% and 1% of the patients with and without LVSI, respectively, (p = 0.001). Any independent prognostic factor could not be detected in the multivariate analysis. Only LVSI and tumor grade were associated with DFS and disease-specific survival (DSS), respectively, in the 686 patients with stage IA endometrial cancer in the univariate analysis, since these associations could not be shown in multivariate analysis.     

Is lymph vascular space involvement an independent prognostic factor in early cervical cancer?

OBJECTIVE: To determine whether lymph vascular space involvement (LVSI) in women with early cervical carcinoma is an independent prognostic factor. METHODS: The literature was reviewed using Medline and known literature to determine if LVSI is an independent risk factor as determined by multivariant analysis with survival being the end point in patients undergoing radical hysterectomy and pelvic lymphadenopathy. RESULTS: A total of 25 articles were identified that satisfied the evaluation criteria. Only three (12%) identified LVSI as an independent risk factor while 88% and 61% of those evaluated, noted lymph node metastasis and tumor size/depth of invasion to be significant risk factors for survival. CONCLUSIONS: Using LVSI as the sole determining factor for consideration of post radical hysterectomy radiotherapy appears questionable.     

Prognostic factors associated with radical hysterectomy failure

Two hundred seventy-five patients who underwent radical hysterectomy and pelvic lymphadenectomy for FIGO stage IB carcinoma of the cervix between 1961 and 1982 were retrospectively analyzed to identify specific risk factors associated with treatment failure. Patients were classified as high or low risk on the basis of tumor spread to pelvic lymph nodes or surgical margins. Thirty-eight patients had tumor involvement of pelvic nodes or surgical margins. Despite postoperative whole pelvis radiation therapy in 88% of patients, 13 (34.2%) developed recurrence. All patients with involved nodes or margins who recurred died of disease. Patients with pelvic lymph node or surgical margin involvement clearly constitute a high risk group and should be considered candidates for some form of adjuvant therapy. Two hundred thirty-seven patients had negative nodes and clear surgical margins. There were 18 recurrences (7.6%) in this group. Pathologic specimens were reviewed to evaluate additional histologic criteria which might identify those patients at greatest risk for tumor recurrence in this low risk group. Patients whose tumors contained vascular-lymphatic space invasion or adenomatous histologic components recurred more frequently than patients whose tumors did not (P less than 0.05). Eighty-three percent of low risk patients who recurred had tumors with at least one of these features. Degree of differentiation and depth of invasion did not correlate with risk of recurrence. Prospective randomized trials are needed to determine the effectiveness of postoperative adjuvant therapy for patients at risk for recurrent disease.     

What is the difference between squamous cell carcinoma and adenocarcinoma of the cervix? A matched case–control study

The objective of this study was to investigate the efficacy of treatment strategies in patients with adenocarcinoma (AC) of the cervix and compare it with those with squamous cell carcinoma (SCC) of the cervix. Women with FIGO (1994) stage IB1 AC, especially pathologic tumor size of 2-4 cm, treated with class III hysterectomy, were compared with those with SCC treated with comparable strategy in a case-controlled study. Eighty patients (20 cases, 60 controls) were analyzed. Lymphvascular space invasion (P = 0.01) and lymph node metastasis (P = 0.07) were more frequent in patients with SCC than in those with AC. However, there was no significant difference in depth of stromal invasion (P = 0.51) and invasion of the parametrium (P = 0.44) between two groups. And there was also no statistically significant difference in disease-free survival (P = 0.86) and overall survival (P = 0.89) between two groups. Primary radical surgery followed by adjuvant therapy, same as for SCC, would be acceptable for AC with pathologic tumor size of 2-4 cm. Although it was difficult to determine whether AC recurred more systemically, more effective treatment strategies than those currently available for AC should be considered to reduce the systemic recurrence.     

Improved survival in surgical stage I patients with uterine papillary serous carcinoma (UPSC) treated with adjuvant platinum-based chemotherapy

OBJECTIVE: Uterine papillary serous carcinoma (UPSC) is an aggressive form of endometrial cancer characterized by a high recurrence rate and a poor prognosis. Prior studies evaluating treatment of UPSC have been limited by small numbers of patients and inclusion of partially staged patients. The purpose of this study was to evaluate the efficacy of adjuvant platinum-based chemotherapy and vaginal cuff radiation in a large cohort of surgical stage I UPSC patients. METHODS: We retrospectively reviewed 74 stage I patients with UPSC who underwent complete surgical staging at our institution between 1987 and 2004. RESULTS: Stage IA patients were divided into two groups: patients with no cancer in the hysterectomy specimen (defined as no residual uterine disease) and patients with cancer in the hysterectomy specimen (defined as residual uterine disease). Stage IA patients with no residual uterine disease had no recurrences, regardless of adjuvant therapy (n = 12). Stage IA patients with residual uterine disease who were treated with platinum-based chemotherapy had no recurrences (n = 7). However, 6 of 14 (43%) stage IA patients with residual uterine disease who did not receive chemotherapy recurred. The 15 patients with stage IB UPSC who received platinum-based chemotherapy had no recurrences but 10 of the 13 (77%) stage IB patients who did not receive chemotherapy recurred. One of the 7 patients with stage IC UPSC who received platinum-based chemotherapy recurred and 4 of the 5 (80%) stage IC patients who did not receive chemotherapy recurred. Overall platinum-based chemotherapy was associated with improved disease-free survival (P < 0.01) and improved overall survival (P < 0.05) in patients with stage I UPSC. None of the 43 patients who received radiation to the vaginal cuff recurred locally, but 6 of the 31 (19%) patients who were not treated with vaginal radiation recurred at the cuff. CONCLUSIONS: Platinum-based chemotherapy improves the disease-free and overall survival of patients with stage I UPSC and vaginal cuff radiation provides local control. Stage IA UPSC patients with no residual uterine disease can be observed but concomitant platinum-based chemotherapy and vaginal cuff radiation (referred to as chemoradiation) should be offered to all other stage I UPSC patients.
