Re-classification of uterine cervical cancer cases treated with radical hysterectomy based on the 2018 FIGO staging system

ObjectiveWe re-classified patients with stage IB–II disease (based on the 2008 system) and compared the outcomes with those obtained after using the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system.Materials and methodsWe reviewed the data of 154 patients with cervical cancer who underwent radical hysterectomy at our hospital during 2006–2016. Pathological, histological, and radiographic data were used to re-classify the cases based on the 2018 FIGO system. We compared these outcomes to those obtained after using the 2008 FIGO assignments. Overall survival (OS) was calculated from primary therapy initiation until death or the last follow-up examination.ResultsThe histological types were squamous cell carcinoma (108 cases) and others (46 cases). The 2008 FIGO system assignments were stage IB1, IB2, IIA1, IIA2, and IIB (87, 27, seven, five, and 28 patients, respectively). The new 2018 FIGO system assignments were stage IB1, IB2, IB3, IIA1, IIA2, IIB, and IIIC1 (52, 26, 16, six, three, 21, and 30 patients, respectively). Re-classification to stage IIIC1 disease was observed for previously assigned stage IB1, IB2, IIA1, IIA2, and IIB cases (10, seven, two, two, and nine cases, respectively). The median OS durations based on the 2018 FIGO system were 71.7, 61.1, and 62.3 months for patients with stage IB1, IB2, and IB3 (p = 0.04) disease, respectively. The new stage IB3/IIA2/IIB cases had longer OS than the old stage IB2/IIA2/IIB cases. A positive computed tomography (CT) finding of nodal involvement was observed in 37% of cases with pathological confirmation of pelvic lymph node (LN) involvement. Using CT to identify pelvic LN metastasis had a sensitivity of 37% and specificity of 93%.ConclusionThe 2018 FIGO staging system for cervical cancer after radical hysterectomy showed a better ability to differentiate survival outcomes. However, the image evaluation method should be reconsidered.     

Accuracy of frozen section examination of pelvic lymph nodes in patients with FIGO stage IB1 to IIB cervical cancer

OBJECTIVE: We evaluated the accuracy of intraoperative frozen section histology of pelvic lymph nodes in patients with FIGO stage IB1 to IIB cervical cancer. METHODS: A total of 96 patients with cervical cancer FIGO stage IB1 to IIB had surgery including systematic pelvic or pelvic and paraaortic lymphadenectomy and intraoperative frozen section examination of pelvic lymph nodes at our department between January 1997 and October 2001. The results of frozen section were compared with those of final histology. RESULTS: A total of 1044 pelvic lymph nodes underwent intraoperative frozen section examination and node metastases were found in 29 patients (30%). Final histopathology yielded a total of 5042 lymph nodes and identified an additional seven patients with node metastases for a false negative rate of 19%. The specificity and the positive predictive value of frozen section examination were 100%; the negative predictive value was 90% (60/67). CONCLUSION: The diagnostic accuracy of frozen section analysis of pelvic lymph nodes should be considered when intraoperative decisions are based on its results.     

Radical hysterectomy for stage IIB cervical cancer: a review

Patients with stage IIB cervical cancer in some countries in Europe and Asia especially in Japan are usually treated with radical hysterectomy and pelvic lymphadenectomy. Extrauterine diseases, ie, nodal metastases, parametrial invasion, and intraperitoneal spread, can be readily identified. We present the literature review of radical hysterectomy in stage IIB cervical cancer by searching data since 1980 from Medline, and we found that the parametrial involvement of patients in this stage was only 21-55%, the incidence of pelvic node metastases was about 35-45%, and 5-year survival rate was between 55% and 77%. Lymph node metastases and the number of positive nodes were significant prognostic factors of patients in this stage.     

Extended radical hysterectomy in early-stage carcinoma of the uterine cervix: tailoring the radicality

The question of whether surgical treatment in early-stage cervical cancer should be aggressive or restricted to less radical techniques is still controversial. To answer this question it was thought useful to investigate the correlation of parametrial lymph node metastases with extension and stage of disease. Two-hundred and sixty-three consecutive primary radical surgical procedures were performed in our institute in clinical stage IB or stage IIA cervical cancer. Positive parametrial nodes were found in 6.9% of cases: 5% in stage IB (3% in the proximal part of the parametrium and 2% in the distal part, near the pelvic wall) and 16.3% in stage IIA (7% proximal and 9.3% distal) ( P = 0.0193). During a median follow-up period of 92 months, disease recurred in 17.1% and 17.6% of cases, in negative and positive parametria, respectively. The 5-year overall and disease-free survival rates were 80.4% and 81.6% for patients with negative and positive parametria, respectively. From this experience it is concluded that the extent of radical hysterectomy should be related to the extent of the disease on the basis of modern knowledge of the pattern of spread. The principal key to prognosis remains pelvic and paracavoaortic nodal status.     

Surgery after concurrent chemoradiotherapy and brachytherapy for the treatment of advanced cervical cancer: morbidity and outcome: results of a multicenter study of the GCCLCC (Groupe des Chirurgiens de Centre de Lutte Contre le Cancer)

OBJECTIVES: To evaluate the morbidity and therapeutic value of surgery after concurrent chemoradiotherapy and brachytherapy in a multicentric series of patients with advanced cervical cancer. METHODS: Patients with stage IB2 to IVA cervical cancer treated with concurrent chemoradiotherapy and pelvic radiotherapy followed by brachytherapy and surgery from seven participating French comprehensive cancer centers were enrolled. The surgical treatment consisted of a hysterectomy, which ranged from radical hysterectomy to anterior pelvic exenteration, and lymph node resection. Acute toxicity, pathological response, overall, and disease-free survival were assessed for each pathological response to therapy. RESULTS: One hundred seventy-five patients were enrolled from September 1987 to June 2002. The median age was 44 years [27;75]. Patients distribution according to clinical classification was as follows: 41 stage IB2, 18 IIA, 77 IIB, 12 IIIA, 14 IIIB, and 13 IVA. Forty-six patients experienced 51 postoperative complications. Thirty-three patients experienced grade 2 morbidity (18.9%, 33/175), among whom 19 experienced urinary complications (57.5%, 19/175). No post treatment mortality was observed. Grade 3 toxicity rate was 6.9% (12/175). Pathological complete response rate was 38% (67/175). After a median follow-up of 36 months, overall survival and disease-free survival were significantly better in patients who had a pathological complete response to therapy than those who achieved a partial pathological response (P < 0.0001). CONCLUSION: Surgery after concurrent chemoradiotherapy and brachytherapy for advanced cervical cancer leads to an acceptable morbidity. Furthermore, surgery allows evaluation of the pathological response to therapy and improves local control in the case of partial pathological response.     

How important is removal of the parametrium at surgery for carcinoma of the cervix?

OBJECTIVES: The aims of this study were (1) to determine the incidence and factors predictive for pathologic parametrial involvement in clinical stage IA1/2 and IB1 cervical cancer after radical surgery and (2) to identify a population at low risk for pathologic parametrial involvement. METHODS: All patient information was collected prospectively and extracted from a cervical cancer radical surgery database. Selection criteria for surgery were generally based upon tumor size, with the cutoff for surgery between 3 and 4 cm. Parametrial involvement (PI) was defined as either positive parametrial lymph nodes (PMLN) or malignant cells in the parametrial tissue (PT) (including lymphovascular channels) by either contiguous or discontiguous spread. Statistical analysis included the chi2 test, the Wilcoxon rank test, and the Mantel-Haentzel test. RESULTS: Between July 1984 and January 2000, 842 patients underwent radical surgery for clinical stage IA1/2 and IB1 cervical cancer at our center. Forty-nine patients (6%) had positive pelvic lymph nodes. Thirty-three patients (4%) had pathologic PI, 8 in the PMLN and 25 in the PT (none had both). PI was associated with older age (42 vs 40 years, P < 0.04), larger tumor size (2.2 vs 1.8 cm, P < 0.04), higher incidence of capillary-lymphatic space invasion (85% vs 45%, P = 0.0004), tumor grades 2 and 3 (95% vs 65%, P = 0.001), greater depth of invasion (18.0 vs 5.0 mm, P < 0.001), and pelvic lymph node metastases (44% vs 5%, P < 0.0001). The incidence of PI in patients with tumor size < or =2 cm, negative pelvic lymph nodes, and depth of invasion < or =10 mm was 0.6%. CONCLUSION: Pathologic parametrial involvement in clinical stage IA1/2 and /IB1 cervical cancer is uncommon. Acknowledging that almost all patients with pelvic lymph node metastases and a high proportion of patients with tumor invasion >10 mm will receive adjuvant radiation regardless of the radicality of surgery, a population at low risk for pathologic parametrial involvement can be identified. These patients are worthy of consideration for studies of less radical surgery performed in conjunction with pelvic lymphadenectomy.     

Nerve-sparing radical hysterectomy for stage IA2-IIB cervical cancer: 5-year survival of 501 consecutive cases

OBJECTIVE: The purpose of this study was to assess the 5-year survival and morbidity in cases with radical hysterectomy and pelvic lymphadenectomy with pre- and postoperative irradiation performed to treat Stage IA2-IIB cervical cancer. METHODS: During a 10(1/2)-year period between July 1990 and December 2000, 501 consecutive radical hysterectomies with bilateral pelvic lymphadenectomy were performed by the same gynecological surgeon in Stage IA2, IB, IIA and IIB cervical cancer. The patients were treated by pre- and postoperative irradiation as well. RESULTS: Apart from recurrence, perioperative complications were minimal with no long-term morbidity. The absolute 5-year survival rates for the patients in Stage IA2, IB1, IB2, IIA and IIB were 94.4%, 90.7%, 84.1%, 71.1%, and 55.4%, respectively. The respective 5-year survival rates for patients without or with lymph node metastasis were 94.5% and 33.3% in Stage IB2, 81.7% and 48.7% in Stage IIA and 70.2% and 36.5% in Stage IIB, respectively. CONCLUSIONS: Nerve-sparing radical hysterectomy with pelvic lymph node dissection and pre- and postoperative irradiation remains the treatment of choice for most patients with early-stage and even Stage IIB cervical cancer. The radicalism and extent of lymph node dissection and parametrial resection should be individualized and tailored to tumor- and patient-related risk factors.     

Prognostic factors in surgically treated stage IB–IIB carcinoma of the cervix with negative lymph nodes

Comerci G, Bolger BS, Flannelly G, Maini M, de Barros Lopes A, Monaghan JM. Prognostic factors in surgically treated stage IB–IIB carcinoma of the cervix with negative lymph nodes. Int J Gynecol Cancer 1998; 8: 23–26.
Two hundred and seventy-five females with stage IB–IIB negative lymph node cervical cancer, treated between January 1988 and December 1994 by radical hysterectomy and pelvic lymph node dissection, form the basis of this analysis. The clinical records were reviewed for all patients including histopathology, clinical features at presentation, and follow-up. Tumors were re-staged according to the 1995 FIGO classification.
Median follow-up was 55 months and 85.8% were followed for longer than two years. There were 21 recurrences, 12 of which were true central recurrence (disease-free survival at 5 years: 91.66%). Fifteen of 25 deaths were due to cervical cancer (crude survival at 5 years: 93.27%). In univariate log-rank analysis, stage ( P = 0.005), tumor size ( P = 0.0002), and lymph-vascular space involvement (LVSI) ( P = 0.01) appeared to be statistically significant factors for tumor recurrence. Other factors including age, histology type, differentiation, adjacent cervical intraepithelial neoplasia or cervical glandular intraepithelial neoplasia, and presence of intraepithelial disease at resection margin were not found to be statistically significant. In multivariate analysis (Cox regression) tumor size ( P = 0.02) and LVSI ( P = 0.03) were the only independent variables. In the presence of negative lymph nodes and complete surgical excision, tumor size and LVSI are important predictors of local recurrence.     

Pretreatment tumor diameter/volume and pelvic lymph node status assessed by magnetic resonance imaging for uterine cervical carcinoma treated with concurrent chemotherapy and radiotherapy

Aim:  The aim is to evaluate the prognostic value of tumor diameter, volume and pelvic lymph node status assessed by magnetic resonance imaging (MRI) in patients with uterine cervical carcinoma patients treated with concurrent chemotherapy and radiotherapy.
Methods:  Ninety-eight patients diagnosed with stage IB to IIIB cervical carcinoma were entered into the study. Tumor diameter was evaluated in T2-weighted image. The tumor volume was calculated by the equation (volume = width × length × height × π/6) as an ellipsoid approximation. Univariate and multivariate analyses were performed to identify the prognostic factors for overall survival (OS), disease-free survival (DFS), pelvic control (PC) and distant metastasis-free survival (DMFS).
Results:  The 5-year OS, DFS, PC and DMFS rate were 59.8%, 57.3%, 67.9% and 78.8%, respectively. Using univariate analyses, large MRI tumor diameter (≥4 cm), large tumor volume (≥30 mL), pelvic enlarged pelvic lymph nodes, large clinical diameter (≥4 cm) and International Federation of Gynecology and Obstetrics (FigO) stage showed a statistically significantly unfavorable influence on OS and DFS. In multivariate analyses, large tumor volume affected OS, DFS, PC and DMFS, and enlarged pelvic lymph nodes also affected OS.
Conclusion:  Tumor volume and enlarged pelvic lymph nodes determined by pretreatment MRI examinations were significant prognostic factors for patients with invasive cervical carcinoma treated with concurrent chemotherapy and radiotherapy.     

Is there a benefit of pretreatment laparoscopic transperitoneal surgical staging in patients with advanced cervical cancer?

OBJECTIVE: At present, cervical cancer remains the only gynecologic tumor, which is staged by clinical examination according to FIGO. This is associated with a high percentage of over- and understaging of tumor extent. With the operative, especially laparoscopic staging, exact information about intraabdominal tumor spread, lymph node metastases, and involvement of adjacent organs is possible. However, the advantage of operative staging is still discussed controversially. The aim of this study is to describe the laparoscopic transperitoneal staging procedure in patients with cervical cancer and their oncologic outcome after primary chemoradiation. METHODS: From November 1994 to October 2003, 456 consecutive patients with histologically confirmed primary cervical cancer were admitted to the Department of Gynecology of the Friedrich-Schiller-University Jena, Germany. Out of these, 84 patients with locally advanced tumor (tumor size>or=4 cm) and/or lymph node involvement and/or tumor infiltration to bladder or rectum were selected by a standardized laparoscopic staging procedure for primary chemoradiation. Data of surgery, chemoradiation, and follow-up were analyzed retrospectively for these patients. RESULTS: The mean age of the patients was 54 years (26-80), and the mean body-mass-index was 24.8 (17.9-42.2). Preoperative clinical evaluation showed a stage distribution according to FIGO with stage IB1 in 15.5%, IB2 in 15.5%, IIA in 8.3%, IIB in 23.8%, IIIA in 8.3%, IIIB in 21.4%, IVA in 6%, and IVB in 1.2%. In 15 out of 84 (17.8%) patients, intraabdominal tumor spread was diagnosed by laparascopy. In 24 out of 84 (28.5%) patients, invasion of bladder and/or rectum was proven histologically after biopsy. In 60 out of 84 (71%) patients, lymph node metastases were confirmed histologically. In 2 out of 13 patients with FIGO-stage Ib1, skip metastases in infrarenal paraaortic lymph nodes were seen. Removal of more than 5 pelvic and/or more than 5 positive paraaortic lymph nodes was associated with significant improvement of overall survival. According to the histological findings following laparoscopic staging in 36 out of 84 (43%) patients, a higher tumor stage was diagnosed. If tumor involvement of lymph nodes is also included, an upstaging in 73/84 (87%) of patients has to be noted down. Downstaging was not necessary in any patient following laparoscopic evaluation. CONCLUSION: Only operative staging gives exact information about tumor extension in patients with locally advanced and/or nodal positive cervical cancer and allows individual treatment planning. This can be done successfully by a transperitoneal laparoscopic approach without serious adverse effects delaying chemoradiation. Debulking of tumor-involved lymph nodes significantly improves overall survival and should be performed prior to primary chemoradiation. Laparoscopic staging should be the basis for all treatment studies in order to group patients according to true tumor extent.     

Clinical significance of tumor size in stage IB and II carcinoma of the uterine cervix

Abstract. Kawagoe T, Kashimura M, Matsuura Y, Sugihara K, Toki N, Aoki T. Clinical significance of tumor size in stage IB and II carcinoma of the uterine cervix.
The purpose of the present study was to investigate the correlation between tumor size and prognosis in stage IB and II cervical cancer and to elucidate the adequacy of new FIGO staging system for cervical cancer. The subjects included 128 patients with cervical cancer (stage IB = 86, IIA = 18, and IIB = 24) who had undergone radical hysterectomy. The largest tumor size of the pathology specimen was measured in two dimensions, and the correlation between tumor size and prognosis was investigated. In addition, tumor size of the pathology specimen was compared with the largest tumor diameter measured by MRI in stage IB cancers. Patients with a tumor size greater than 3 cm² had a significantly worse 5-year survival rate (63%) when compared to those with tumor size no greater than 3 cm² (96%) ( P < 0.0001). Multivariate analysis revealed that independent prognostic factors were tumor size ( P = 0.003) and lymph node metastasis ( P = 0.015). By regression analysis, the largest tumor size of the pathology specimen was relatively well correlated with the largest tumor diameter by MRI in stage IB cancers; 3 cm² of tumor size in the pathology specimen corresponded to 3.4 cm of tumor diameter by MRI. The adequacy of new FIGO staging system was considered relatively acceptable.     

Parametrial spread of cervical cancer in patients with negative pelvic lymph nodes.

OBJECTIVE: We studied the incidence and prognostic implications of parametrial involvement according to tumor volume in a series of cervical cancer patients with negative pelvic lymph nodes. METHODS: We reviewed a series of 351 node-negative patients with stage IB, IIA, or IIB cervical cancer treated with class III radical hysterectomy. The surgical specimens were processed as step-serial giant sections and tumor volume was calculated. Overall, 180 patients had tumors <5 mL, 120 had tumors of 5-20 mL, and 51 had tumors >20 mL. Parametrial involvement was classified as continuous, discontinuous, or involvement of blood vessels or lymph nodes and according to location as medial or lateral. A total of 302 patients had squamous cell tumors and 49 had adenocarcinomas. The mean duration of follow-up was 9.3 years. RESULTS: Overall, 44 of 351 patients (12.5%) had parametrial involvement. The rate of parametrial involvement in patients with tumors <5, 5-20, and >20 mL was 6.7, 12.5, and 33%, respectively. Isolated involvement of the medial parametrium increased with tumor size (3.8, 8.3, and 27.5%, respectively), whereas isolated involvement of the lateral parametrium was seen in 2.2, 1.6, and 0% of the cases. Involvement of both the medial and the lateral portions of the parametrium was seen in 0.5, 2.5, and 5.9% of the specimens, respectively. There were no differences in the rate of parametrial involvement between squamous cell carcinomas and adenocarcinomas. The 5-year disease-free survival rates in patients without or with parametrial involvement were 90.2% vs 90%, 91.7% vs 92.9%, and 84.7% vs 67%, respectively. CONCLUSION: The lateral portion of the parametrium can be involved in patients with cervical cancer and negative pelvic lymph nodes, but this is uncommon. In this series of patients treated with type III radical hysterectomy, parametrial involvement had no influence on disease-free survival.     

Treatment of cervical cancer with adjuvant chemotherapy versus adjuvant radiotherapy after radical hysterectomy and systematic lymphadenectomy

Aim:  To compare the clinical efficacy focused on post-treatment morbidity between adjuvant chemotherapy (CT) and pelvic radiotherapy (RT) after radical hysterectomy for patients with cervical cancer.
Methods:  A total of 125 patients with cervical squamous cell carcinoma who underwent radical hysterectomy and pelvic lymphadenectomy at Hokkaido University Hospital between 1991 and 2002 were enrolled in the study for retrospective analysis. Seventy patients with recurrent risk factors, including deep stromal invasion, lymph vascular space invasion, parametrial invasion, lymph node metastasis (LNM), and bulky tumor (≥4 cm), received adjuvant therapy; 42 were treated with RT, and 28 were treated with CT. Almost all patients with multiple LNM received RT. Analyses were also performed on a subgroup of 50 patients without multiple LNM (23 RT, 27 CT). Clinical efficacy of post-treatment morbidity and survival was evaluated.
Results:  Because there were more patients with multiple LNM in the RT group, we analyzed disease-free survival in 50 patients without multiple LNM. The 3-year disease-free survival rate was 82.6% with RT and 96.3% with CT ( P  = 0.16). Postoperative bowel obstruction was significantly more frequent in the RT group versus the CT ( P  = 0.007) and no-therapy ( P  = 0.0026) groups. Urinary disturbance was also more frequent in the RT group than in the CT ( P  = 0.0016) and no-therapy ( P  = 0.089) groups.
Conclusion:  CT has the equivalent therapeutic effect as RT with fewer postoperative complications for patients with intermediate risks. A prospective randomized trial is needed to compare CT combined with radical hysterectomy and pelvic lymphadenectomy to RT or chemoradiotherapy.     

Pattern of lymph node metastasis and the optimal extent of pelvic lymphadenectomy in FIGO stage IB cervical cancer

AIM: To evaluate the distribution pattern of lymph node metastasis and to determine the optimal extent of pelvic lymphadenectomy (LA) in FIGO stage IB cervical cancer. METHODS: The medical records of 187 patients with FIGO stage IB cervical cancer from March 1996 to December 2002 were reviewed retrospectively. The distribution pattern and risk factors of lymph node metastases were analyzed in 31 patients with lymph node metastases confirmed surgically. One hundred patients, who underwent type III hysterectomy with pelvic LA but did not receive any adjuvant treatment, were analyzed to evaluate whether the extent of LA affected the prognosis of FIGO stage IB cervical cancer. Type I LA included the external iliac nodes, hypogastric nodes, obturator nodes, and parametrial nodes. Type II LA included the pelvic nodes described in type I LA, the common iliac nodes, gluteal nodes, deep inguinal nodes and sometimes the presacral nodes. RESULTS: Solitary lymph node metastasis confined to one node group was seen in the obturator, external iliac or hypogastric lymph nodes. All patients with lymph node metastases at multiple sites had metastasis in at least one of these lymph-node groups. There was no significant difference in disease-free survival and overall survival in patients without pathologic high-risk factors according to the type of pelvic LA. CONCLUSION: The extent of LA should be adjusted to reduce complications and not to affect adversely the prognosis of FIGO stage IB cervical cancer patients without pathologic high-risk factors.     

Prevalence and prognostic significance of COX-2 expression in stage IB cervical cancer

OBJECTIVES: To evaluate the prevalence of cyclooxygenase-2 (COX-2), correlation with various clinicopathologic factors and prognostic significance of COX-2 in stage IB cervical cancer patients. METHODS: 89 paraffin-embedded specimens of patients with stage IB cervical cancer underwent radical hysterectomy and pelvic lymphadenectomy at King Chulalongkorn Memorial Hospital during 1 January 1997-31 December 2002 and were stained with polyclonal goat antiserum against COX-2 using immunohistochemical method. Medical records were reviewed; clinicopathological variables were retrieved and used for analysis. RESULTS: The prevalence of positive COX-2 expression in stage IB cervical cancer in this study was 49.4%. Positive COX-2 expression in cervical adenocarcinoma was higher than squamous cell carcinoma (86.7% versus 40.6%, P < 0.05) and significantly expressed when lymph node metastasis was presented (100% versus 46.4%, P < 0.05). However, COX-2 expression was possibly associated with parametrial involvement (80% versus 47.6%, P > 0.05). There was no correlation between COX-2 expression and patient's age, tumor size, depth of stromal invasion and lymphovascular space invasion. Five-year disease free survival and 5-year overall survival in patients with positive COX-2 expression were 81% and 98% which were not differed from patients with negative COX-2 expression (92% and 95%, P > 0.05). CONCLUSIONS: Strong correlation was found in cervical adenocarcinoma and lymph node metastasis. However, COX-2 expression failed to demonstrate as a significant prognostic factor in stage IB cervical cancer.     

Prediction of cervical involvement in endometrial cancer by hysteroscopy

Objective This study evaluated the ability of hysteroscopy to preoperatively predict cervical involvement in endometrial cancer.Methods The records of 110 surgically staged consecutive endometrial cancer patients treated at our institution from 1997 to 2003 were retrospectively analyzed. Data on demographics, preoperative staging procedures, surgical pathology reports, and adjuvant treatments were retrieved.Results Fourteen (12.7%) patients had cervical involvement (stage II) according to the surgical pathology report, of whom nine (8.1%) had stage IIA and five (4.6%) had stage IIB. Clinical evaluation by speculoscopy and palpation had failed to reveal any indication of cervical involvement. Preoperative diagnostic hysteroscopy procedures were included. None of the hysteroscopy procedures revealed any suspicious lesion in the cervical canal. Conclusion Hysteroscopy and clinical examination fail to adequately predict cervical involvement in endometrial carcinoma. Fractional D&C appears to be the best method until a more effective alternative becomes available.Drs. Almog and Gutman contributed equally to this paper.     

Identifying local tumor variables for operable node-negative, margin-free patients with bulky cervical carcinoma of FIGO stage IB, IIA and IIB without adjuvant therapies

PURPOSE: To identify local risk factors for FIGO IB, IIA and IIB bulky cervical squamous cell carcinoma (tumor size > or = 4 cm) patients with node-negative, margin-free tumors treated by radical hysterectomy, pelvic lymph node and para-aortic lymph node dissections without adjuvant therapies. MATERIALS AND METHODS: Thirty-four patients were recruited between 1976 and 1989 because they all declined any postoperative adjuvant therapy. The pathology reports showed that all the specimen margins were free from cancer cells with no para-aortic or pelvic lymph node metastases. The survival interval was calculated starting from the time of surgical intervention to the time of death or the end of this study in the year 2000. RESULT: Tumor variables including cell differentiation, depth of stromal invasion, parametrial invasion, vaginal invasion, uterine body invasion, age, and FIGO stage were analyzed. Only vaginal invasion showed statistical significance for decreasing patient disease-free survival in both univariate and multivariate analyses with p values of 0.003 and 0.002, respectively. CONCLUSION: For node-negative and margin-free patients with bulky cervical squamous cell carcinoma with operable stage IB and IIB, surgical intervention alone could suffice when no vaginal invasion is noted plus an 85% survival rate could be achieved. A prospective pilot study should be initiated although this study showed an excellent survival rate which is perhaps due to the limited number of cases.     

Conservative management of early stage cervical cancer: is there a role for less radical surgery?

Objectives

The utility of parametrial resection in women with early stage cervical cancer is controversial. In patients with favorable pathologic characteristics such as tumor size < 2 cm and the absence of lymphovascular space invasion, the rate of parametrial involvement is very low. More conservative surgical approaches have therefore been suggested. The objective of this report is to review the existing literature in this area and to describe an ongoing prospective study evaluating the safety and efficacy of conservative surgery in women with early stage cervical cancer.

Methods

We performed a search of PubMed for English language articles published between 1970 and 2010 using the MeSH terms “cervical cancer”, “conservative surgery”, and “cone biopsy”.

Results

Several retrospective studies have shown that < 1% of patients with early stage cervical cancer with favorable pathologic characteristics have parametrial involvement. In addition, approximately 60% of patients undergoing radical trachelectomy have no residual disease in the final pathologic specimen. Recent studies have reported on the feasibility and safety of performing less radical surgery consisting of pelvic lymphadenectomy with cone biopsy, simple trachelectomy or simple hysterectomy in women with stage IA1 to IB1 cervical carcinoma. In addition, a prospective, multi-center, international trial is currently being performed to evaluate the outcomes of performing pelvic lymphadenectomy with conservative surgery (simple hysterectomy or cervical conization) in patients with favorable pathologic characteristics. Neoadjuvant chemotherapy followed by conservative surgery is also being explored as an option for patients with larger tumors and other pathologic characteristics that do not meet the criteria to perform conservative surgery alone.

Conclusions

The rate of parametrial involvement in women with early stage cervical cancer with favorable pathologic characteristics is low. Should the results of ongoing studies be favorable, conservative surgery could become the standard of care for certain women with early stage cervical cancer.     

Value of fine needle aspiration biopsy in cervical cancer

Correct staging qualification, especially evaluation of parametrium is very useful in choosing of adequate method of treatment, and thereby in patients' survival. OBJECTIVE: The aim of study was estimation of the value of fine needle aspiration biopsy in transvaginal ultrasonography assistant in preoperative assessment of parametria in cervical cancer. We compared parametrial infiltration before treatment and to verified and confirmed staging in cervical cancer postoperatively by histopathology. MATERIAL AND METHOD: 64 women with cervical cancer in stage Ib, were included in the study. Assessment of parametrial invasion before treatment was performed by fine needle aspiration biopsy in endovaginal ultrasound assistants. The sonographic evaluation of parametria was performed by Siemens Sonoline Versa Pro with transvaginal 7 MHz mechanical transducer with the biopsy guide 14 cm long. All of patients with cervical cancer in stage Ib were operated on Wertheim-Meigs hysterectomy. The preoperative findings were compared with data obtained by histopathology findings. There were evaluated sensitivity, specificity and diagnostic accuracy of this method. RESULTS: Accuracy of fine needle aspiration biopsy of parametrial involvement was 89%, sensitivity-70%, specificity-92.6%, PPV-63.6%, NPV-94.3%. CONCLUSIONS: Transvaginal ultrasonography is superior to routine clinical examination in the assessment of parametria. Sensitivity of fine needle biopsy with ultrasound assistance is higher then of gynecological examination and ultrasound alone. Correct preoperative diagnosis may improve staging, treatment and indirectly, survival patients with cervical cancer.     

High-risk group in node-positive patients with stage IB, IIA, and IIB cervical carcinoma after radical hysterectomy and postoperative pelvic irradiation

OBJECTIVE: The goal of this study was to identify risk factors in patients with node-positive stage IB, IIA, and IIB cervical carcinoma after radical hysterectomy with pelvic lymph node dissection and postoperative irradiation. METHODS: Two hundred forty-two patients with FIGO stage IB, IIA, and IIB cervical carcinoma underwent radical hysterectomy with pelvic lymph node dissection; pathological analysis of the surgical specimen showed positive lymph nodes in 59 patients. These 59 patients were further treated with postoperative radiotherapy. Eighteen patients were in stage IB, 4 in stage IIA, and 37 in stage IIB. Histological tumor type, tumor size, lymph-vascular space invasion, parametrium infiltration, number of positive nodes, and involvement of common iliac nodes were assessed for correlation with cancer recurrence. RESULTS: When all these variables were assessed in the Cox proportional regression analysis, parametrium infiltration (P = 0. 0199) and number of positive nodes (two or more nodes) (P = 0.0483) revealed the factor correlating significantly with disease-specific survival. Based on these two factors, node-positive patients could be divided into low-risk (n = 11), intermediate-risk (n = 29), and high-risk (n = 19) groups. The 5-year disease-specific survival for the low-risk group was 100% which was significantly better than the 39.1% for the high-risk group (P = 0.0012). CONCLUSION: For patients in the high-risk group, it may be worthwhile to consider new strategies to improve survival.
