Lymphatic vessel involvement is predictive for lymph node metastasis and an important prognostic factor in endometrial cancer.

BACKGROUND: Lymphovascular space involvement is reported to be an important risk factor in endometrial cancer. This study was conducted to evaluate the separate prognostic effects of lymphatic invasion and venous invasion on the outcomes of patients with endometrial cancer. METHODS: From 2006 to 2013, 189 histologically confirmed endometrial cancer patients were examined. To study the venous invasion (v) of the endometrial cancer, Victoria blue-H&E staining-which positively stains the elastic fibers of vessels-was performed. Immunohistochemical staining with D2-40 was used to study the lymphatic invasion (ly) of the endometrial cancer. RESULTS: The median age of the patients was 57 (range 25-84) years. ly(+) and/or v(+) patients were significantly more likely to present an advanced cancer stage, G3 tumor, and deep myometrial invasion than ly(-)/v(-) patients. The incidence of lymph node metastasis was high in ly(+) patients, and that of ovarian metastasis was high in v(+) patients. Lymphatic vessel invasion was significantly correlated with regional lymph node metastasis. We found a significantly higher incidence of distant metastasis in ly(+) patients. Most recurrences in ly(+)/v(-) patients occurred in lymph nodes, while those in ly(+)/v(+) patients occurred mainly at distant organs. Finally, the prognosis was significantly poorer for ly(+) patients, in whom lymphatic invasion was an independent prognostic factor along with distant metastasis. CONCLUSIONS: Our study suggests that by separately evaluating lymphatic invasion and blood vessel invasion in endometrial cancer cases, useful information for predicting lymph node metastasis and recurrence sites as well as prognostic information can be obtained.

Therapy-free interval has prognostic value in patients with recurrent cervical cancer treated with chemotherapy following definitive concurrent chemoradiotherapy.

PURPOSE: Patients with cervical cancer recurrence after concurrent chemoradiotherapy (CCRT) who are not candidates for surgical resection or salvage radiotherapy have a dismal prognosis. The predictive factors for the effects of chemotherapy and prognostic factors in these patients were analyzed. METHODS: We collected data for patients with recurrent cervical cancer who were primarily treated with CCRT between 2000 and 2013. Among them, 57 patients treated with only systemic chemotherapy were analyzed for the overall survival (OS), the overall response rate (ORR), and prognostic factors. RESULTS: The median age was 47 years. Inside the irradiated field recurrence occurred in 24, outside in 20 and both in 13 patients. Time to recurrence after the CCRT (i.e., therapy-free interval; TFI) were <6 months in 11, 6-12 months in 15, ≥12 months in 23 patients, and persistent disease in 8 patients. The median OS was 18 months and ORR was 15.7%. Those with a longer TFI showed a tendency for better ORR (p = 0.051) and those receiving a taxane-containing regimen showed significantly higher ORR (p = 0.0232). Multivariate analysis revealed a significant correlation between the median OS and TFI (HR = 4.688, 95% CI = 2.178-11.10, p < 0.0001) and chemotherapy response (HR = 20.08, 95% CI = 3.936-368.4, p < 0.0001). Furthermore, even in patients with stable disease, the median OS increased corresponding to the length of the TFI (p < 0.0001). CONCLUSIONS: TFI has predictive value for response to chemotherapy and prognosis of patients with recurrent cervical cancer after definitive CCRT.

Secondary uterine carcinosarcoma after concurrent chemoradiotherapy for cervical cancer: Case reports.

•Secondary uterine sarcomas occur in < 1% of patients treated with CCRT.•Secondary uterine sarcomas can occur > 5 years from CCRT.•The median survival period from the secondary tumor occurrence was only 4 months.•All our patients had heterologous carcinosarcoma of the uterine corpus.

Concurrent weekly cisplatin versus triweekly cisplatin with radiotherapy for locally advanced squamous-cell carcinoma of the cervix: a retrospective analysis from a single institution.

OBJECTIVE: To compare patients with cervical cancer who were primarily treated with concurrent chemoradiotherapy (CCRT) using 20 mg m-2 CDDP for 5 days every 3 weeks with weekly regimens of 40 mg m-2. METHODS: We retrospectively analyzed 185 patients with Stage IB-IVA squamous-cell carcinoma of the cervix who were treated with CCRT between 2005 and 2013 at our hospital. The CCRT regimen consisted of cisplatin (CDDP) at 20 mg m-2 for 5 days every 3 weeks or 40 mg m-2 weekly, administered concomitantly with RT. RESULTS: The median age was 50 years (range: 22-70 years) in the triweekly group and was 50.5 years (range: 28-70 years) in the weekly group. The 5-year overall survival rate in the triweekly and weekly groups were 82.0% and 83.3%, respectively (p = 0.851); their disease-free survival rate was 79.6% and 78.1%, respectively (p = 0.672). In the triweekly group, 56 patients (50.9%) had grade 3/4 leukopenia, which was significantly higher than that of 11 patients (15%) in the weekly group (p < 0.0001). CONCLUSION: The weekly CDDP regimen for CCRT seems better in patients with International Federation of Gynecology and Obstetrics Stages IB-IVA squamous-cell carcinoma of the cervix. Advances in knowledge: The weekly CDDP regimen for CCRT seems better in patients with International Federation of Gynecology and Obstetrics Stages IB-IVA squamous-cell carcinoma of the cervix.

Recurrent female adnexal tumor of probable Wolffian origin treated with debulking surgery, imatinib and paclitaxel/carboplatin combination chemotherapy: A case report.

In view of the small number of recurrent and metastatic cases of female adnexal tumors of probable Wolffian origin (FATWO), there is a distinct lack of evidence to support recommendations regarding treatment. In the present study, a 37-year-old female was diagnosed with a left adnexal tumor and underwent a left salpingo-oophorectomy (SO). The tumor was found to arise from the left tubal fimbria and extend to the posterior leaf of the broad ligament. Pathological examination identified a number of solid, tubular and cystic architectures, with areas of hyalinization, hemorrhage and necrosis. Immunohistochemistry detected that the tumor cells were positive for cytokeratin (CK)7, vimentin, inhibin and calretinin, and negative for CK20, epithelial membrane antigen, and the estrogen and progesterone receptors. Thus, the patient was diagnosed with FATWO. Following 15 months, the patient developed recurrent tumors and subsequently underwent a total abdominal hysterectomy, a right SO and extirpation of the disseminated tumors, but with incomplete debulking. The tumor cells were immunoreactive for KIT. As there are a limited number of treatment options and few reported cases, limiting the therapy recommendations, imatinib mesylate was administered for 6 months and the tumors were temporarily stabilized for 4 months until the disease progressed. The patient underwent a further debulking surgery that did not achieve complete debulking and was subsequently administered a combination chemotherapy of paclitaxel and carboplatin. This regimen resulted in an almost complete response after 10 cycles. The tumors continued to decrease in size, and the tumors in the left side of the Douglas pouch and the right para-colic gutter were no longer detectable. To the best of our knowledge, the current study is the first to report carboplatin and paclitaxel combination therapy demonstrating a response of this degree to recurrent FATWO following the failure of imatinib treatment. However, surgical debulking remains the most effective treatment for FATWO when is it is possible. The precise role of chemotherapy, radiotherapy and molecular-targeting therapy in the treatment of recurrent or metastatic FATWO remains to be elucidated, and therefore, novel strategies to overcome this disease must be prioritized.

Prognostic Factors and Treatment Outcome for Patients with Stage IVB Cervical Cancer.

AIM: We report a retrospective evaluation for patients with stage IVB cervical cancer in order to identify survival rates and to improve our current practice. PATIENTS AND METHODS: We analyzed 85 patients with stage IVB cervical cancer. For patients appropriate for radical treatment, a combination of external-beam radiotherapy and intracavitary brachytherapy was delivered with/without chemotherapy. Patients with distant metastasis were treated using systemic chemotherapy or palliative radiotherapy. RESULTS: Forty-two patients were treated using radiotherapy alone, 31 using chemotherapy followed by radiotherapy, eight using chemotherapy alone, and four using best supportive care. The 5-year overall survival rate was 9.9%. Multivariate analysis revealed leukocytosis and a poor performance status were independent prognostic factors. Of the 43 patients without these prognostic factors, patients with only lymph node metastasis had a 5-year overall survival rate of 40.5%. CONCLUSION: Radical treatment should be considered in patients who have only lymph rode metastasis and are without leukocytosis and a poor performance status.

Diffuse Venous Malformation of the Uterus in a Pregnant Woman with Klippel-Trénaunay Syndrome Diagnosed by DCE-MRI.

Background. We experienced a rare case of a pregnant woman with Klippel-Trénaunay syndrome complicated with diffuse venous malformation of the uterus. This is the first report on the usefulness of dynamic contrast-enhanced-MRI for the diagnosis of diffuse venous malformation of the uterus. Case Presentation. A 23-year-old woman presented with convulsions and talipes equinus position of both lower limbs at 11 weeks of gestation. At 27 weeks, ultrasonography demonstrated tubular echolucent spaces throughout the myometrium. Dynamic MRI at 37 weeks revealed that the myometrial lesion was enhanced slowly and showed homogeneous enhancement even on a 10 min delayed image. Taken together with unilateral foot hypertrophy, varices, and port-wine stain, the patient was diagnosed as having Klippel-Trénaunay syndrome complicated with diffuse venous malformation of the pregnant uterus. The patient underwent elective cesarean section because of severe dystonia. The lower uterine segment was thickened and heavy venous blood flow was observed at the incision. Histological diagnosis of the myometrial biopsy specimen was venous malformation. Conclusions. Both diffuse venous malformation and Klippel-Trénaunay syndrome during pregnancy can involve considerable complications, in particular, massive bleeding during labor. Women who suffer from this syndrome should be advised about the risk of complications of pregnancy.

Prognostic factors in patients with vulvar cancer treated with primary surgery: a single-center experience.

Vulvar cancer is a relatively rare disease. The aim of this study was to investigate prognostic factors in vulvar squamous cell carcinoma patients treated with primary surgery. Forty cases of vulvar squamous cell carcinoma treated with primary surgery were retrospectively analyzed. Overall survival (OS) and disease-specific survival (DSS) were calculated using the Kaplan-Meier method and prognostic factors were analyzed by multivariate analyses. The median age was 68 years. The FIGO stage distribution was as follows: 18 cases (45.0 %) in stage I, four cases (10.0 %) in stage II, 15 cases (37.5 %) in stage III, and three cases (7.5 %) in stage IV. A radical local excision was performed in 15 patients, and radical vulvectomy in 25 patients, and seven of these patients were treated with postoperative RT. The 5-year DSS rate was 72.6 %, and the 5-year OS rate was 70.3 %. Age and surgical margin ≤5 mm were independent prognostic factors for OS, and positive inguinal LN metastasis and surgical margin ≤5 mm were identified as independent prognostic factors for DSS. Complete radical excision is important regardless of operation mode. Adjuvant treatment should be considered for inguinal LN positive patients.

Radiotherapy- or radical surgery-induced female sexual morbidity in stages IB and II cervical cancer.

OBJECTIVE: The objective of this study was to evaluate the sexual function in cervical cancer survivors after radiotherapy (RT) or radical surgery (RS). METHODS: This was an observational and cross-sectional study. The Female Sexual Function Index (FSFI) self-reported questionnaires were distributed to 175 patients after RT (RT group) or RS (RS group) and 521 healthy women (control) between 2011 and 2012. Sexual functions were compared among these 3 groups. RESULTS: Eligible 92 patients (46 in RT group, 46 in RS group) and 148 control subjects were included for analysis. There was a significant difference in median (range) FSFI total score of 5.5 (3.6-34.7) in the RT group, 18.9 (3.4-31.2) in the RS group, and 22.1 (2-34.2) in the control group (P < 0.001). The median FSFI total score in the RT group was significantly lower than that in the control group (P < 0.001). Six sexual domains (desire, arousal, lubrication, orgasm, satisfaction, pain) were all significantly affected in the RT group, and no significant differences, except pain, were observed in the RS group as compared with the control group. CONCLUSIONS: Interventions involving counseling and rehabilitation for female sexual function should be provided in cervical cancer survivors, especially after RT.

Concurrent chemoradiotherapy for non-bulky stage IB/II cervical cancer without pelvic node enlargement.

BACKGROUND: Concurrent chemoradiotherapy (CCRT) has not been extensively studied in patients with small cervical cancer tumors with no pelvic node enlargement. PATIENTS AND METHODS: We retrospectively analyzed 55 patients with stage IB1-IIB cervical cancer and tumors of ≤40 mm with no pelvic node enlargement treated with radiotherapy (RT)-alone. RESULTS: Cancer recurred in seven patients. Patient age (≤63 years) was identified as an independent factor for better disease-free survival (DFS) (p=0.027), and tumor size (≥25 mm) had a tendency to correlate with reduced locoregional DFS (p=0.089) by the Cox hazard model. Among patients aged 63 years or less, cancer recurred in five out of 18 patients with tumors of ≥25 mm, but in only one of 10 patients with tumors of ≤24 mm. CONCLUSION: In patients with stage IB1-IIB cervical cancer and small tumors with no node enlargement, CCRT may provide a better disease control for the group aged 63 years or less and with tumor size of 25 mm or more.

Long-term results and prognostic factors in patients with stage III-IVA squamous cell carcinoma of the cervix treated with concurrent chemoradiotherapy from a single institution study.

BACKGROUND: We evaluated the longer-term efficacy and safety of concurrent chemoradiotherapy (CCRT) incorporating high-dose-rate intracavitary brachytherapy (HDR-ICBT) with a lower cumulative radiotherapy (RT) protocol and analyzed prognostic risk factors for survival among patients with FIGO stage III-IVA squamous cell carcinoma (SCC) of the cervix. PATIENTS AND METHODS: Ninety-nine patients with FIGO stage III-IVA SCC of the cervix between 1997 and 2008 were treated with CCRT using cisplatin 20 mg/m(2) for 5 days every 3 weeks or 40 mg/m(2) weekly. Acute and late toxicities were evaluated. Overall survival (OS) and disease-free survival (DFS) were estimated by the Kaplan-Meier method. The Cox proportional hazard model was used for multivariate analysis. RESULTS: Median age was 53.5 years. Median follow-up period was 58 months (range 6-170 months). Pathologically complete response was achieved in 93 patients (96.9%). The 5-year OS and DFS were 72.0 and 69.3%, respectively. The 5-year local and distant DFS were 83.0 and 75.1%, respectively. Thirty-one patients (31.3%) experienced recurrence. Multivariate analysis showed that tumor size and pretreatment hemoglobin level remained an independent risk factor for OS and DFS. Acute toxicity was moderate. In terms of late adverse effects, 2 patients (2.0%) suffered from grade 4 late intestinal toxicity because of radiation enterocolitis, with both requiring intestinal surgery. CONCLUSIONS: Our study demonstrates that the CCRT schedule in patients with FIGO stage III-IVA SCC is efficacious and safe. In addition, the assessment of tumor size and pretreatment anemia can provide valuable prognostic information.

Concurrent chemoradiotherapy with paclitaxel and cisplatin for adenocarcinoma of the cervix.

BACKGROUND: It is unclear whether cisplatin-based concurrent chemoradiotherapy (CCRT) has the same effect on adenocarcinoma as on squamous cell carcinoma. PATIENTS AND METHODS: We retrospectively analyzed data for 32 patients with stage IIB-IVA cervical adenocarcinoma who were treated with radiotherapy (RT) or CCRT. Fourteen patients were treated with RT, 8 with CCRT using cisplatin alone (CCRT-P), and 10 with CCRT using cisplatin plus paclitaxel (CCRT-TP). RESULTS: Complete response was achieved in 7/14 patients in the RT group, 4/8 patients in the CCRT-P group, and 9/10 patients in the CCRT-TP group. Ten out of the 14 patients in the RT, 7/8 patients in the CCRT-P, and 2/10 patients in the CCRT-TP groups experienced locoregional recurrence. The 5-year overall survival rate in the RT, CCRT-P, and CCRT-TP groups was 7.1%, 25.0%, and 74.1%, respectively (p=0.0094). CONCLUSION: The present study demonstrated that CCRT-TP achieved much better local control for adenocarcinoma of the cervix, leading to a decrease in locoregional recurrence.
