Objective: Concurrent chemoradiotherapy (CCRT) is the primary treatment for locally advanced cervical cancer. We studied prognostic factors for patients treated with CCRT. Methods: We retrospectively reviewed records of 85 consecutive patients with cervical cancer who were treated with CCRT between 2002 and 2011, with external beam radiation therapy, intracavitary brachytherapy, and platinum-based chemotherapy. Survival data were analyzed with Kaplan-Meier methods and Cox proportional hazard models. Results: Of the 85 patients, 69 patients (81%) had International Federation of Gynecology and Obstetrics (FIGO) stage III/IV disease; 25 patients (29%) had pelvic lymph node enlargement (based on magnetic resonance imaging), and 64 patients (75%) achieved clinical remission following treatment. Median maximum tumor diameter was 5.5 cm. The 3- and 5-year overall survival rates were 60.3% and 55.5%, respectively. Cox regression analysis showed tumor diameter >6 cm (hazard ratio [HR], 2.3; 95% confidence interval [CI], 1.2 to 4.6), pelvic lymph node enlargement (HR, 2.2; 95% CI, 1.1 to 4.5), and distant metastasis (HR, 10.0; 95% CI, 3.7 to 27.0) were significantly and independently related to poor outcomes. Conclusion: New treatment strategies should be considered for locally advanced cervical cancers with tumors >6 cm and radiologically enlarged pelvic lymph nodes. © 2015.

Objective: All patients with stage IB1 cervical cancer do not need to undergo parametrectomy. Some low-risk criteria for parametrial involvement (PI) have been proposed based on pathological findings. The aim of this study was to determine pretreatment risk factors for PI in stage IB1 cervical cancer. Methods: We retrospectively reviewed 115 patients with stage IB1 cervical cancer who underwent radical hysterectomy or radical trachelectomy. Magnetic resonance imaging (MRI) was performed and serum concentrations of squamous cell carcinoma antigen (SCC-Ag) and cancer antigen 125 (CA-125) were determined in all patients before initial treatment. The following pretreatment factors were investigated: histological variant, maximum tumor diameter, tumor volume (volume index), pelvic lymph node enlargement, and serum tumor markers. Logistic regression analysis was used to select the independent risk factors for PI. Results: Eighteen of the 115 patients (15.7%) were pathologically diagnosed with PI. Multivariate analysis confirmed the following independent risk factors for PI: MRI-based tumor diameter ≥25 mm (odds ratio [OR], 9.9; 95% confidence interval [CI], 2.1 to 48.1), MRI-based volume index >5,000 mm3 (OR, 13.3; 95% CI, 1.4 to 125.0), and positive serum tumor markers SCC-Ag >1.5 ng/mL or CA-125 ≥35 U/mL (OR, 5.7; 95% CI, 1.3 to 25.1). Of 53 patients with no risk factors for PI, none had PI. Conclusion: Less radical surgery may become one of the treatment options for stage IB1 cervical cancer patients with MRI-based tumor diameter <25 mm, MRI-based volume index <5,000 mm3, and negativity for SCC-Ag and CA-125. © 2015.

Objective: Type II endometrial cancers include uterine papillary serous carcinoma (UPSC) and clear cell endometrial cancer (CC). Given their relative rarity, aggressive nature, and poor prognosis, little is known about the risk of subsequent malignancies at other sites. Our objective was to determine if women with UPSC or CC are at increased risk of subsequent malignancies. Methods: Women diagnosed with UPSC or CC were identified from the SEER (Surveillance Epidemiology and End Results) Program from 1973 to 2005. Cases with a second gynecologic malignancy were excluded. Using SEER * Stat software, standardized incidence ratios (SIRs) of subsequent malignancies were calculated. Results: A total of 8045 and 1740 patientswere diagnosed with UPSC and CC, respectively. Four hundred sixty-one (5.7%) of the UPSC cases were diagnosed with at least 1 additional nongynecologic malignancy. Significant associations were found with the following malignancies: the renal pelvis, soft-tissue sarcomas, acutemyeloid leukemia, the bladder, and colon. Seventy-eight CC cases (4.5%) were diagnosed with at least 1 additional malignancy. In comparison with the baseline population risk, there was no statistically significant increased risk of any subsequent malignancy with a primary diagnosis of CC. Conclusions: This is the first large population-based analysis of second primary malignancies after type II endometrial cancers. Uterine papillary serous carcinoma is associated with increased risks of certain subsequent malignancies, and providers should be aware of these when following up patients with this diagnosis, especially those with stage I disease. In contrast, no such associations were found with CC in this cohort. © 2013 by IGCS and ESGO. Source
