A multi-institutional cohort study of adjuvant therapy in stage I-II uterine carcinosarcoma

ObjectiveTo evaluate the impact of adjuvant post-operative therapy in women with early stage uterine carcinosarcoma.MethodsAfter IRB approval was obtained at all sites, a multi-center retrospective study of women with FIGO stage I–II uterine carcinosarcoma diagnosed from 1997 to 2007 was conducted. Post-operative treatment included observation (OBS), radiation (RT), chemotherapy (CT) alone or with RT (CT + RT). Data analyzed included demographic and pathologic factors, adjuvant therapy outcomes, and time-to-event information. The Kaplan–Meier method was used to estimate time-to-event functions. Cox regression modeling was used to examine the impact of selected covariates on progression free survival (PFS), and overall survival (OS).Results111 women were identified: 94 (85%) had stage I and 17 (15%) had stage II uterine carcinosarcoma. Forty-four women (40%) did not receive adjuvant therapy (OBS), 29 (26%) women had adjuvant CT, 23 (20%) women underwent RT and 15 (14%) women underwent RT + CT. Seventy-three patients were alive without disease and 38 had progressed or died at the close of data collection. In multivariate analysis, CT (p = 0.003), LVSI (p < 0.0001) and a pre-existing cancer (p = 0.004) were most predictive of PFS. LVSI was predictive of shortened OS (p = 0.01).ConclusionsIn women with FIGO stage I–II uterine carcinosarcoma, adjuvant chemotherapy is associated with improved PFS compared to radiation or observation alone. Ongoing clinical trials will clarify the role of chemotherapy in women with this disease.     

Adjuvant radiation therapy is associated with improved overall survival in high-intermediate risk stage I endometrial cancer: A national cancer data base analysis

Purpose

Adjuvant radiation therapy (RT) was shown to improve local control in patients with high-intermediate risk (HIR) stage I endometrial cancer (EC) in randomized trials. Overall survival (OS) was not significantly different with adjuvant RT in these trials or subsequent meta-analyses; however, they were underpowered to assess OS. We used the National Cancer Data Base (NCDB) to examine the impact of adjuvant RT on OS in HIR EC patients.

A retrospective assessment of outcomes of chemotherapy-based versus radiation-only adjuvant treatment for completely resected stage I-IV uterine carcinosarcoma

PurposeTo determine the progression-free survival (PFS) and overall survival (OS) in a cohort of patients who received either platinum-based chemotherapy with or without radiation therapy (pelvic or WAI), or RT alone.MethodsMemorial Sloan-Kettering Cancer Center (MSKCC) electronic medical records from 8/1/1995 to 10/3/2007 were reviewed for patient age, diagnosis date, type of primary surgery, residual disease at the completion of primary surgery, FIGO stage, treatment details, dates of progression and death, and site(s) of first recurrence. PFS and OS by stage (I/II v III/IV) and by treatment type (chemotherapy with or without RT v RT alone) were determined using landmark analyses 8 weeks after surgery. Patients who received chemotherapy with or without RT (pelvic or abdominal) or RT alone (pelvic or abdominal) were included in the analysis. Both groups were allowed to have received intravaginal radiation therapy (IVRT).ResultsForty-nine patients met study criteria. Thirty-eight/49 patients received chemotherapy: 23/38 (60.5%) received paclitaxel-carboplatin; 7/38 (18.4%) received ifosfamide-platinum; 8/38 (21.0%) received other chemotherapy. FIGO stage was: I = 15 (31%); II = 5 (10%); III = 21 (43%); IV = 8 (16%). Three-year PFS for the entire cohort was 24%. Three-year OS for the entire cohort was 60%. Three-year median PFS time for the entire cohort was 15 months (95% CI: 11–25 months). Three-year median OS time for the entire cohort was 67 months (95% CI: 23–89 months). Three-year PFS for stages I–II was 43% v 14% for stages III–IV (HR = 1.98 [0.9–4.33]); P = 0.082. Three-year OS for stages I–II was 68% v 55% for stages III–IV (HR = 1.26 [0.47–3.41]); P = 0.648. Three-year PFS for chemotherapy with or without RT was 35% v 9% for RT alone (HR = 1.74 [0.79–3.85]); P = 0.164. Three-year OS for chemotherapy with or without RT was 66% v 34% for RT alone (HR = 2.02 [0.77–5.33]); P = 0.146.ConclusionsOur study corroborates GOG 150 results, and shows that paclitaxel-carboplatin appears to be an efficacious adjuvant chemotherapy regimen for completely resected uterine carcinosarcoma. The role of adjuvant RT in addition to chemotherapy warrants further investigation.     

Twenty-year review of radiotherapy for vaginal cancer: an institutional experience

ObjectiveTo evaluate clinical outcome, prognostic factors and chronic morbidity with radiotherapy for vaginal cancer treatment.Materials and methods68 patients with vaginal cancer treated by radical or adjuvant radiotherapy (RT) were selected. Five with rare subtypes of histopathology and 8 with adenocarcinoma were excluded from this study. 76.4% of the remainder had early-stage diseases (stage I: 14, II: 28, III: 9, and IV: 4). The patients in the years from which they were treated were almost evenly distributed (1st 5 years: 13, 2nd: 14, 3rd: 16, and 4th: 12). There were four treatment groups: external beam radiotherapy (EBRT) alone (n = 18), brachytherapy (BT) alone (n = 4), EBRT and BT (n = 30), and surgery plus RT (n = 3).ResultsMedian follow-up was 50.3 months ranging from 3 to 213 months. 5-year overall survival (OS) was 55.6%, disease-specific survival (DSS) was 77.3%, disease-free survival was 74.2%, and local control was 87.7%. Independent prognostic factors for DSS and OS were tumor stage, site and size (p < 0.05). Late radiation toxicity was minimal in the bladder (4.6%) and bowel (4.6%). Vaginal morbidity was observed in 35 patients (63.6%). It was lowest in the BT alone (0%), and highest in the EBRT and BT group (82.1%), especially for those received more than 70 Gy (p = 0.05, Odds ratio = 4.64, 95% confidence interval: 1.01–21.65).ConclusionThis retrospective review suggested that tumor stage, site, and size were important prognostic factors in patients with vaginal cancer. Higher radiation dose was associated with more frequent vaginal toxicity.     

Adjuvant radiation for early stage endometrial cancer with lymphovascular invasion

ObjectiveTo determine the impact of the decrease in use of postoperative pelvic external beam radiation (EBRT) in favor of intravaginal RT (IVRT) alone in patients with early stage endometrial cancer who had lymphovascular invasion (LVI).MethodsBetween 11/1988 and 5/2005, 126 patients treated with simple hysterectomy and postoperative RT had a final pathologic diagnosis of stage IB–IIB adenocarcinoma of endometrioid histology with documented LVI. The patients were divided into two groups based on the era of treatment, (early era: 1988–1996, vs. late era: 1997–2005), in order to best capture the shift away from the routine use of EBRT in favor of surgical staging and IVRT.ResultsOf the 126 patients, 35% (n = 44) were treated in the early era and 65% (n = 82) in the late era. The two groups were balanced in regards to age, race, depth of myometrial invasion, histologic grade, and cervical involvement. Significantly more patients had surgical staging and received IVRT alone in the late than early era (p = 0.0001, 0.004, respectively). The rate of pelvic control was 93% for the early era compared to 97% for latter era (p = 0.3). There was no significant impact of the treatment era on vaginal control, disease-free survival, or overall survival.ConclusionsThese data suggest that the mere presence of LVI need not trigger the use of pelvic EBRT. Instead, the decision on whether to omit EBRT in patients with LVI should be made in the context of a patient's competing risk factors and comorbid conditions.     

Health related quality of life and symptoms after pelvic lymphadenectomy or radiotherapy vs. no adjuvant regional treatment in early-stage endometrial carcinoma: A large population-based study

ObjectivesRoutine lymphadenectomy (LA) in early stage endometrial cancer does not improve survival. However, in the absence of lymph node metastasis, radiotherapy (RT) could be withheld and hence could result in less morbidity. Our aim was to evaluate health related quality of life (HRQL) in endometrial cancer survivors that received routine pelvic LA without RT compared to no LA, but RT in the presence of risk factors.MethodsStage I–II endometrial cancer survivors diagnosed between 1999 and 2007 were selected from the Eindhoven Cancer Registry. Survivors completed the SF-36 and the EORTC-QLQ-EN24. ANCOVA and multiple linear regression analyses were applied.Results742 (77%) of the endometrial cancer survivors returned a completed questionnaire. 377 (51%) had received no LA nor RT (LA?RT?), 198 (27%) had received LA+RT?, 153 (21%) LA?RT+ and 14 patients (2%) had received both. LA+ women reported as higher lymphedema symptom scores (25 vs. 20, p = 0.04). Women who were treated with RT reported higher gastrointestinal symptom scores vs. those who did not (23 vs. 16, p = 0.04). HRQL scales were comparable between all four treatment groups.ConclusionDespite distinct symptom patterns among women who received LA or RT, no clinically relevant differences in HRQL were observed when compared to women not receiving adjuvant therapy. Using LA to tailor adjuvant pelvic radiotherapy and prevent over-treatment in low-risk patients cannot be recommended.     

The outcome and efficacy of adjuvant chemotherapy alone in patients with stage IIIA endometrial carcinoma with solitary adnexal involvement: A retrospective single-institution study

ObjectivesThe appropriate adjuvant therapy for patients with endometrial carcinoma with solitary adnexal involvement is unclear. We conducted a retrospective single-institution study to evaluate the outcome and efficacy of adjuvant chemotherapy alone in this population.MethodsAll patients with endometrial carcinoma who received primary surgical treatment between January 1999 and May 2010 were reviewed. The patients who were diagnosed with stage IIIA disease based only on isolated adnexal involvement and treated with surgical procedures followed by adjuvant chemotherapy alone were included. Demographic, clinicopathologic, treatment and outcome data were collected. Recurrence and survival were analyzed.ResultsAmong 1453 reviewed patients, 67 patients were identified. The median age was 48 years. All patients were treated with platinum-based adjuvant chemotherapy, with the majority (36/67, 53.7%) receiving paclitaxel plus carboplatin. The total number of cycles of chemotherapy administered was 305 (median four cycles/person). Most of the chemotherapy related toxicities were mild or moderate. The median follow-up time was 76 months. Eight patients experienced recurrence. The majority of initial relapses were distant (7/8, 87.5%), characterized by liver metastases (3/8, 37.5%). The 5-year disease-free survival (DFS) and overall survival (OS) rates were 89.6% and 91.9%, respectively. Multivariate analysis confirmed that grade 3 tumor was an independent predictor of worse DFS and OS (HR = 5.19, P = 0.048; HR = 6.55, P = 0.037, respectively).ConclusionPatients with stage IIIA endometrial carcinoma with solitary adnexal involvement have favorable outcomes. Adjuvant chemotherapy alone may be effective and feasible for these patients.     

Patterns of adjuvant radiation usage and survival outcomes for stage I endometrial carcinoma in a large hospital-based cohort

Objective

Two randomized trials have demonstrated a local control advantage in the absence of a survival advantage for the addition of adjuvant radiation therapy (RT) to surgery in patients with stage I endometrial adenocarcinoma (EC). This study analyzed the National Cancer Data Base (NCDB) to evaluate the impact of adjuvant RT on overall survival (OS) for patients with stage I EC.

Risk factors for poor prognosis in microinvasive adenocarcinoma of the uterine cervix (IA1 and IA2): a pooled analysis

ObjectiveTo identify adverse risk factors for FIGO IA1 and IA2 cervical adenocarcinoma.MethodsPubMed was used to identify all microinvasive adenocarcinoma cases. Case specific data pooled for 35 “high risk” microinvasive adenocarcinoma (MIAC), defined as cases with lymph node or lymphovascular space involvement, positive surgical margins, or recurrence was compared with 478 “low risk” cases abstracted from the SEER database (1988–1997). Statistical methods included non-paired t and Fisher's Exact tests.ResultsSurvival for 1A1 and 1A2 MIAC is 99% and 98%, respectively. Significantly more 1A2 patients underwent aggressive radical surgery and received postoperative treatment. Parametrial involvement was rare (1/373 cases). Significantly more “high-risk” cases were of endometrioid histology (6/34 vs. 14/478, p = 0.001), whereas adenocarcinoma (p = 0.046) and mucinous (p = 0.021) tumors were observed in the “low-risk” group. Among the “high-risk” cases with at least 5 years follow-up, 1.4% has recurred or died.ConclusionsEndometrioid histology may be associated with late recurrence and worse survival in stage 1A1 and 1A2 MIAC.     

Uterine adenosarcoma: An analysis on management,outcomes, and risk factors for recurrence

ObjectivesUterine adenosarcoma is a rare malignancy with little data on optimal management. We aimed to clarify the impact of adjuvant therapy in patients with uterine adenosarcoma and identify risk factors for recurrence and death.MethodsWe performed a retrospective review of patients undergoing primary evaluation and treatment for uterine adenosarcoma at a single institution from July 1982 through December 2011. Univariate and multivariate analyses were used to identify prognostic factors for progression-free survival (PFS) and overall survival (OS).ResultsWe identified 100 patients with uterine adenosarcoma, and 74 patients met the inclusion criteria. On multivariate analysis, sarcomatous overgrowth (SO) and lymphovascular space invasion (LVSI) were predictors of worse PFS and OS. Median PFS and OS were 29.4 and 55.4 months for patients with SO, compared to 105.9 and 112.4 months for patients without SO (PFS HR 2.58, 95% CI 1.37–4.84, p = 0.003; OS HR 2.45, 95% CI 1.26–4.76, p = 0.008). Among patients with stage I disease, 17 of 22 patients (77%) with SO and 8 of 37 patients (22%) without SO had a recurrence (p < 0.001). Among patients with stage I disease with SO, adjuvant therapy appeared to be associated with longer PFS and OS, but these differences were not statistically significant (PFS, 46.7 vs. 29.4 months, p = 0.28; OS, 97.3 vs. 55.4 months, p = 0.18).ConclusionIn patients with uterine adenosarcoma, the presence of SO or LVSI confers a higher risk of recurrence. We did not identify an optimal treatment strategy for patients with SO, but adjuvant therapy may be associated with prolonged PFS.     

The impact of race on outcomes of patients with early stage uterine endometrioid carcinoma

ObjectivesThe purpose of the present study was to determine whether racial disparity exists between African American (AA) and non-African American (NAA) patients with uterine endometrioid carcinoma who received similar multidisciplinary management.MethodsWe identified 766 patients with endometrioid adenocarcinoma 2009 FIGO stages I–II who underwent hysterectomy. Patients were divided into two groups; AA and NAA. Recurrence-free survival (RFS), disease specific survival (DSS) and overall survival (OS) for two groups were calculated.ResultsMedian follow-up was 5.1 years. 27% were AA and 73% were NAA. All patients underwent hysterectomy and oophorectomy. 80% had peritoneal cytology examination and 69% underwent lymphadenectomy. AA patients were more likely to have higher grade tumors, and higher incidence of lymphovascular space involvement (LVSI). Although the two groups were balanced with regards to surgical staging and adjuvant treatment received, the 5-year RFS and DSS were significantly lower in AA compared to NAA patients (91% vs 84%, p = 0.030; 95% vs 88%, p = 0.011, respectively). Overall survival was not significantly different between the two groups. On multivariate analysis, after adjusting for other prognostic factors, race (AA vs NAA) was not a significant predictor of outcome. Grade 3 tumors and the presence of LVSI were the only two independent predictors of RFS and DSS with p ≤ 0.001 and p ≤ 0.001, respectively.ConclusionIn this large hospital-based study, AA race was associated with a higher incidence of adverse pathological features and worse recurrence-free and disease-specific survival. However, on multivariate analysis race was not an independent prognostic factor. Further studies are needed to elucidate possible underlying molecular mechanisms for these poorer outcomes.     

Rapidly growing ovarian endometrioid adenocarcinoma involving the vagina: a case report

ObjectiveWe present a rare case of a very rapidly growing stage IV ovarian endometrioid adenocarcinoma involving the uterine cervix and vagina without lymph node involvement.Case ReportA 43-year-old woman visited the hospital with complaints of lower abdominal discomfort and vaginal bleeding over the previous 3 months. Serum levels of tumor marker CA 125 and SCC antigen (TA-4) were normal. On magnetic resonance imaging, a 7.9 × 9.7 cm heterogeneous mass with intermediate signal intensity was observed in the posterior low body of the uterus. Two months ago, a computed tomography scan revealed an approximate 4.5 × 3.0 cm heterogeneously enhanced subserosal mass with internal ill-defined hypodensities. A laparotomy, including a total abdominal hysterectomy with resection of the upper vagina, bilateral salpingo-oophorectomy, pelvic and para-aortic lymph node dissection, appendectomy, total omentectomy, and biopsy of rectal serosa was performed. A histological examination revealed poorly differentiated endometrioid ovarian adenocarcinoma with vaginal involvement. The patient had an uncomplicated post-operative course. After discharge, she completed six cycles of adjuvant chemotherapy with paclitaxel (175 mg/m²) and carboplatin (300 mg/m²) and has remained clinically disease-free until June 2010.ConclusionEpithelial ovarian cancer may grow very rapidly. The frequent measurement of tumor size by ultrasonography may provide important information on detection in a subset of ovarian carcinomas that develop from preexisting, detectable lesions.     

A phase II trial of carboplatin and docetaxel followed by radiotherapy given in a "Sandwich" method for stage III, IV, and recurrent endometrial cancer

ObjectiveTo determine feasibility and efficacy of administering docetaxel and carboplatin chemotherapy followed by pelvic radiotherapy and then consolidation chemotherapy in patients with advanced or recurrent endometrial cancer.MethodsPatients with surgically staged III–IV (excluding IIIA from positive cytology alone) endometrial cancer or biopsy confirmed recurrent disease were eligible. Treatment consisted of 3 cycles of docetaxel (75 mg/m²) and carboplatin (AUC 6) on a q21 day schedule followed by involved field irradiation (45 Gy) ± brachytherapy and three additional cycles of docetaxel and carboplatin. Kaplan–Meier (KM) methods estimated overall survival (OS) and progression free survival (PFS).ResultsForty-two patients enrolled, 7 did not complete therapy. 95% (39/41) had primary disease. Median age = 58 years (range: 21–81 years). 78% (32/41) = endometrioid histology. Stages = 10 IIIA, 21 IIIC, 1 IVA, 7 IVB, (recurrent = 1 IC, 1 IIA). There were 23 non-hematologic and 14 grade 3 and 16 grade 4 hematologic toxicities. Seven patients died following treatment with a median follow-up of 28 months (range: 7–70 months). KM estimates and 95% confidence intervals for OS at 1 year were 95% (82–99%), at 3 years 90% (75–96%), and at 5 years 71% (45–86%). Of the 39 with primary disease, 11 progressed or died within 5 years of study enrollment. KM estimates and 95% confidence intervals for PFS at 1 year were 87% (72–94%), at 3 years 71% (51–83%), and at 5 years 64% (42–80%).Conclusions“Sandwiching” radiation between chemotherapy for advanced or recurrent endometrial cancer merits further development based on the reported PFS and OS.     

A multicenter evaluation of adjuvant therapy in women with optimally resected stage IIIC endometrial cancer

ObjectiveTo determine if there is an advantage to combination chemotherapy and radiation for optimally resected stage IIIC endometrial cancer (EC).MethodsA multicenter retrospective analysis of patients with EC from 1991 to 2008 was conducted. Inclusion criteria were lymph node assessment and optimally resected disease. Recurrence-free (RFS) and overall survival (OS) were analyzed using Kaplan–Meier method and Cox proportional hazards model.Results265 patients with optimally resected stage IIIC EC were identified. Postoperative therapies included radiotherapy in 17% (n = 45), chemotherapy in 17% (n = 46), and both chemotherapy and radiation in 61% (n = 161). Three-year RFS was 56% for chemotherapy alone, compared to 73% for radiation alone, and 73% for combination therapy (p = 0.12). Those receiving chemotherapy alone had the worst 3-year OS (78%) compared to either radiotherapy alone (95%) or combination therapy (90%) (p = 0.005). After adjustment for stage and grade those treated with chemotherapy alone were at a 2.2 fold increased risk of recurrence (95% CI, 1.2 to 4.2; p = 0.02) and 4.0 fold increased risk of death (95% CI, 1.6 to 10.0; p = 0.004) compared to those treated with chemotherapy and radiation. In contrast there was no significant difference in RFS [HR = 1.0 (95% CI, 0.5 to 2.0; p = 0.92)] or OS [HR = 1.1 (95% CI, 0.3 to 3.6; p = 0.91)] for those treated with radiation alone compared to those treated with chemotherapy and radiation.ConclusionAdjuvant therapy with either radiation alone or chemotherapy and radiation was associated with improved outcomes for patients with optimally resected stage IIIC EC compared to those treated with chemotherapy only.     

Prediction of suboptimal primary cytoreduction in primary ovarian cancer with combined positron emission tomography/computed tomography--a prospective study

ObjectiveThe treatment of FIGO stage IB2 cervical cancer is controversial. Our aim was to assess treatment patterns, outcomes, and complications in patients with stage IB2 cervical cancer.MethodsA retrospective study of patients with stage IB2 cervical carcinoma at a single institution between January 1982 and September 2006 was performed. To adequately control treatment variables, we only included patients who underwent their entire treatment at our institution. Toxicity was assessed using NCI Common Toxicity Criteria (CTC).ResultsWe identified 82 patients, of whom 47 met the strict inclusion criteria. Of these, 27 patients (57%) underwent primary radical hysterectomy (RH) and 20 (43%) were treated with definitive radiation/chemoradiation therapy (RT/CRT). Patients selected for RT/CRT had a higher American Society of Anesthesiologist (ASA) score than those selected for surgery (P = 0.037). The 3-year progression free survival rate was 52% for the RH group and 55% for the RT/CRT group (P = 0.977). The 3-year overall survival rates were 72% and 55%, respectively (P = 0.161). Overall, 52% of patients in the RH group received postoperative radiation therapy as part of their adjuvant treatment. CTC grade 3, 4, and 5 complications affected 5 patients (19%) in the RH group and 3 (15%) in the RT/CRT group.ConclusionBoth RH and definitive RT/CRT are adequate management strategies for patients with FIGO stage IB2 cervical cancer. However, there was a subset of patients in whom RH as monotherapy was appropriate. Further studies are needed to evaluate the role of new preoperative models that will accurately identify these patients.     

Associations between p53 overexpression and multiple measures of clinical outcome in high-risk, early stage or suboptimally-resected, advanced stage epithelial ovarian cancers A Gynecologic Oncology Group study

ObjectiveThe Gynecologic Oncology Group (GOG) performed a detailed analysis of p53 overexpression in previously-untreated women with invasive early or advanced stage epithelial ovarian cancer (EOC).MethodsWomen were eligible for the study if they provided a tumor block for translational research and participated in either GOG-157, a randomized phase III trial of three versus (vs.) six cycles of paclitaxel + carboplatin in high-risk, early stage EOC, or GOG-111, a randomized phase III trial of cyclophosphamide + cisplatin vs. paclitaxel + cisplatin in suboptimally-resected, advanced stage EOC. The N-terminal DO-7 p53 antibody was used to examine the expression of the major normal and mutant p53-isoforms. p53 overexpression was defined as ≥ 10% tumor cells exhibiting nuclear staining.Resultsp53 was overexpressed in 51% (73/143) and 66% (90/136) of cases in the GOG-157 and GOG-111 cohorts, respectively. In the GOG-157 cohort, p53 overexpression was not associated with any clinical characteristics or overall survival (OS) but was associated with worse progression-free survival (PFS) (logrank test: p = 0.013; unadjusted Cox modeling: p = 0.015). In the GOG-111 cohort, p53 overexpression was associated with GOG performance status (p = 0.018) and grade (p = 0.003), but not with age, stage, cell type or with tumor response and disease status after primary chemotherapy, PFS or OS. Adjusted Cox regression modeling demonstrated that p53 overexpression was not an independent prognostic factor for PFS or OS in either cohort.Conclusionsp53 overexpression assessed by DO-7 immunostaining is common in early and advanced stage EOC, but has limited prognostic value in women treated with surgical staging and platinum-based combination chemotherapy.     

Postoperative pelvic intensity-modulated radiotherapy and concurrent chemotherapy in intermediate- and high-risk cervical cancer

ObjectiveAccording to national surveys, the use of intensity-modulated radiation therapy (IMRT) in gynecologic cancers is on the rise, yet there is still some reluctance to adopt adjuvant IMRT as standard practice. The purpose of this study is to report a single-institution experience using postoperative pelvic IMRT with concurrent chemotherapy in intermediate- and high-risk early stage cervical cancer.MethodsFrom 1/2004 to 12/2009, 34 patients underwent radical hysterectomy and pelvic lymph node dissection (28 median nodes were removed) for early stage cervical cancer. Median dose of postoperative pelvic IMRT was 50.4 Gy (range, 45–50.4). All patients received concurrent cisplatin.ResultsWith a median follow-up of 44 months, 3 patients have recurred; 1 vaginal recurrence, 1 regional and distant, and 1 distant. The 3- and 5-year disease-free survival (DFS) was 91.2% (95% CI, 81.4–100%) and overall survival (OS) was 91.1% (95% CI, 81.3–100%). All failures and all deaths were in the high-risk group (n = 3/26). There was 32.3% G3–4 hematologic toxicity, 2.9% acute G3 gastrointestinal toxicity, and no acute G3 or higher genitourinary toxicity. There were no chronic G3 or higher toxicities.ConclusionsOncologic outcomes with postoperative IMRT were very good, with DFS and OS rates of > 90% at median follow-up of 44 months, despite a preponderance (76.5%) of high-risk features. Toxicity was minimal even in the setting of an aggressive trimodality approach. Data from this study and emerging data from the Phase II RTOG study (0418) demonstrate the advantages of postoperative IMRT in early stage cervical cancer.     

The effect of maximal surgical cytoreduction on sensitivity to platinum-taxane chemotherapy and subsequent survival in patients with advanced ovarian cancer

ObjectivesLimited information exist about the frequency of micrometastases, their topographic distribution and prognostic impact in patients with cervical carcinoma (CX).MethodsLymph nodes of patients with surgically treated CX, FIGO IB to IIB, with pelvic lymph node involvement, were re-examined regarding the size of metastatic deposits, their topographic distribution within the pelvis. Lymph node status (pN0 vs. pN1mic = metastasis < 0.2 cm vs. pN1 = metastasis > 0.2 cm) was correlated to recurrence free (RFS) and overall survival (OS).Results31.4% of all patients (281/894) represented pelvic lymph node involvement. 22.2.% of the node positive ones showed micrometastases (pN1mic). Most commonly, obturator and internal nodes were affected by pN1mic, without any side differences. Patients with macrometastases (pN1) and micrometastases (pN1mic) represented significant reduced RFS-rate at 5-years (62% [95% CI: 54.2 to 69.8] for pN1 and 68.9% [95% CI: 55.5 to 82.4] for pN1mic) when compared to patients without metastatic disease (91.4% [95% CI: 89.0 to 93.8]; p < 0.001) The 5-years OS-rate was decreased in patients with metastatic disease (pN0: 86.6% [95% CI: 83.7 to 89.5], pN1mic: 63.8% [95% CI: 50.9 to 76.7], pN1: 48.2% [95% CI: 40.4 to 56.0]; p < 0.0001). These differences persisted in detailed analysis within these subgroups. In multivariate analysis, tumor stage, pelvic lymph node involvement and micrometastases were independent prognostic factors.ConclusionsA remarkable number of patients with CX show micrometastases within pelvic nodes. Micrometastatic disease represents an independent prognostic factor. So, all patients with pelvic lymph node involvement, including micrometastatic deposits, might be candidates for adjuvant treatment.     

Postoperative pelvic intensity-modulated radiotherapy in high risk endometrial cancer

ObjectiveAccording to national surveys, the use of intensity-modulated radiation therapy (IMRT) in gynecologic cancers is on the rise, yet there is still some reluctance to adopt adjuvant IMRT as standard practice. The purpose of this study is to report a single-institution experience using postoperative pelvic IMRT with or without chemotherapy in high-risk endometrial cancer.MethodsFrom 11/2004 to 12/2009, 46 patients underwent hysterectomy/bilateral salpingo-oophorectomy for stage I-III (22% stage I/II and 78% stage III) endometrial cancer. Median IMRT dose was 50.4 Gy. Adjuvant chemotherapy was given to 30 (65%) patients.ResultsWith a median follow-up of 52 months, 4 patients recurred: 1 vaginal plus lung metastasis, 2 isolated para-aortic recurrences, and 1 lungs and liver metastasis. Five-year relapse rate was 9% (95% CI, 0–13.6%). Five-year disease-free survival (DFS) was 88% (95% CI, 77–98%) and overall survival (OS) was 97% (95% CI, 90–100%). There were 2 patients with non-hematological grade 3 toxicity: 1 (2%) acute and 1 (2%) chronic gastrointestinal toxicity. In patients treated with IMRT and chemotherapy (n = 30), 5 had grade 3 leukopenia, 8 grade 2 anemia, and 2 grade 2 thrombocytopenia.ConclusionsOncologic outcomes with postoperative IMRT were very good, with DFS and OS rates of > 88% at median follow-up of 52 months, despite a preponderance (78%) of stage III disease. Toxicity was minimal even in the setting of an aggressive trimodality (65% of patients) approach. Data from this study and emerging data from RTOG trial 0418 demonstrate the advantages of IMRT in high-risk endometrial cancer.     

Is the pathologic tumor size associated with survival in early cervical cancer treated with radical hysterectomy and adjuvant radiotherapy?

ObjectiveIn 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system of uterine cervix cancer, size criteria of primary tumor has been revised. This study aimed to evaluate the validity of this new size criteria (<2, 2–4, and ≧4 cm) in patients who underwent radical hysterectomy and adjuvant radiation therapy (RT) for early cervical cancer.Materials and methodsWe retrospectively examined 312 patients who underwent radical hysterectomy and adjuvant RT for early cervical cancer (IB-IIA) from 2001 to 2014. The effects of clinical and pathological factors on disease-free survival (DFS) and overall survival (OS) were evaluated in univariate and multivariate analyses.ResultsAfter a median follow-up of 71.5 months, the 5-year DFS and OS rates were 89.5% and 94.7%, respectively. The primary tumor size was not a significant factor for DFS (p = 0.382) or OS (p = 0.725) in all patients.ConclusionPrimary tumor size was not a significant factor for survival in patients who received hysterectomy and adjuvant RT for early cervical cancer. Adequacy of new tumor size criteria (<2, 2–4, and ≧4 cm) in new 2018 FIGO stage needs to be validated in further studies.
