Prognostic factors for and pattern of lymph-node involvement in patients with operable cervical cancer.

PURPOSE: Lymph node metastases significantly worsen the prognosis in cervical carcinoma. Risk factors-pathological and patient related-could select patients at high risk for lymph node involvement. METHODS: This retrospective analysis was performed by analyzing data from patients with cervical carcinoma treated between 2000 and 2017 at the Department of Obstetrics and Gynecology of the University Hospital Ulm. RESULTS: In total, 261 patients with cervical carcinoma (International Federation of Gynecology and Obstetrics (FIGO) stage IA-IIB) and lymphadenectomy with at least 10 removed lymph nodes were available for analysis. Overall, 86 (33.0%) patients had lymph node metastases; 73 patients had pelvic lymph node metastases only and 13 patients had both pelvic and paraaortic lymph node metastases. Lymph node metastases were found most often in the region of the external iliac artery and obturator fossa, with 57.0% and 54.7% of all 86 node-positive patients, respectively. Univariable analyses showed that presence of lymph node metastases was significantly associated with both preoperative FIGO stage (p = 0.001) and final pathological tumor stage (p < 0.001), status of resection margin (p = 0.002), lymphovascular space invasion (LVSI), (p < 0.001) and vascular space invasion, (p < 0.001). In a multivariable logistic regression model with presence of lymph node metastases (yes/no) as binary response variable, only LVSI (p < 0.001) and body mass index (BMI), (p = 0.035) remained as significant independent predictors of lymph node involvement. Subgroup analyses showed that LVSI was a significant predictive factor for lymph node involvement in patients with a preoperatively assessed FIGO stage < IIB (p < 0.001), but not for patients with a preoperatively assessed FIGO stage ≥ IIB (p = 0.122). CONCLUSIONS: The risk factor LVSI should play an important role in deciding whether an individualized therapy concept is based on escalating or deescalating treatment. In future, the sentinel concept could reduce morbidity and at the same time provide an important prognostic assessment for a subset of cervical cancer patients.

Pelvic exenteration as ultimate ratio for gynecologic cancers: single-center analyses of 37 cases.

BACKGROUND: Pelvic exenterations are a last resort procedure for advanced gynecologic malignancies with elevated risks in terms of patients' morbidity. METHODS: This single-center analysis reports surgical details, outcome and survival of all patients treated with exenteration for non-ovarian gynecologic malignancies at our university hospital during a 13-year time period. We collected data regarding patients and tumor characteristics, surgical procedures, peri- and postoperative management, transfusions, complications, and analyzed the impact on survival outcomes. RESULTS: We identified 37 patients between 2005 and 2013 with primary or relapsed cervical cancer (59.5%), vulvar cancer (24.3%) or endometrial cancer (16.2%). Median age was 60 years and most patients (73%) had squamous cell carcinomas. Median progression-free survival was 26.2 months and median overall survival was 49.9 months. The 5-year survival rates were 34.4% for progression-free survival and 46.4% for overall survival. There were no significant differences in progression-free survival and overall survival with regard to disease entity. Patients with tumor at the resection margins (R1) had a nearly significantly worse progression-free survival (median: 28.5 vs. 7.3 months, HR 2.59, 95% CI 0.98-6.88, p = 0.056) and a significantly worse overall survival (median: not reached vs. 10.9 months, HR 4.04, 95% CI 1.40-11.64, p = 0.010) compared to patients with complete tumor resection (R0). In addition, patients without lymphovascular space invasion had a significantly better progression-free survival (p = 0.017) and overall survival (p = 0.034) then patients with lymphovascular space invasion. We observed complications in 14 patients (37.8%), 10 of those were classified as Clavien-Dindo 3 or 4. There was a trend to worse progression-free survival in patients that suffered complications (p = 0.052). Median total amount of transfused blood products was 4 (range 0-20). CONCLUSION: Pelvic exenteration is a procedure that provides substantial progression-free survival and overall survival improvement and-in selected patients-can even achieve cure in otherwise hopeless clinical situations. Patients need to be offered earnest counseling for sufficient informed consent with realistic expectations what to expect.

Surgical staging and prognosis in serous borderline ovarian tumours (BOT): a subanalysis of the AGO ROBOT study.

BACKGROUND: Incomplete surgical staging is a negative prognostic factor for patients with borderline ovarian tumours (BOT). However, little is known about the prognostic impact of each individual staging procedure. METHODS: Clinical parameters of 950 patients with BOT (confirmed by central reference pathology) treated between 1998 and 2008 at 24 German AGO centres were analysed. In 559 patients with serous BOT and adequate ovarian surgery, further recommended staging procedures (omentectomy, peritoneal biopsies, cytology) were evaluated applying Cox regression models with respect to progression-free survival (PFS). RESULTS: For patients with one missing staging procedure, the hazard ratio (HR) for recurrence was 1.25 (95%-CI 0.66-2.39; P=0.497). This risk increased with each additional procedure skipped reaching statistical significance in case of two (HR 1.95; 95%-CI 1.06-3.58; P=0.031) and three missing steps (HR 2.37; 95%-CI 1.22-4.64; P=0.011). The most crucial procedure was omentectomy which retained a statistically significant impact on PFS in multiple analysis (HR 1.91; 95%-CI 1.15-3.19; P=0.013) adjusting for previously established prognostic factors as FIGO stage, tumour residuals, and fertility preservation. CONCLUSION: Individual surgical staging procedures contribute to the prognosis for patients with serous BOT. In this analysis, recurrence risk increased with each skipped surgical step. This should be considered when re-staging procedures following incomplete primary surgery are discussed.

Age-dependent differences in borderline ovarian tumours (BOT) regarding clinical characteristics and outcome: results from a sub-analysis of the Arbeitsgemeinschaft Gynaekologische Onkologie (AGO) ROBOT study.

BACKGROUND: Approximately one-third of all borderline ovarian tumours (BOT) are diagnosed in patients with child-bearing potential. Detailed information regarding their specific characteristics and prognostic factors is limited. METHODS: Clinical parameters of BOT patients treated between 1998 and 2008 in 24 German centres were retrospectively investigated. Central pathology review and prospective follow-up were carried out. Patients <40 versus ≥40 years were analysed separately and then compared regarding clinico-pathological variables and prognosis. RESULTS: A total of 950 BOT patients with a median age of 49.1 (14.1-91.5) years were analysed [280 patients <40 years (29.5%), 670 patients ≥40 years (70.5%)]. Fertility-preserving surgery was carried out in 53.2% (149 of 280) of patients <40 years with preservation of the primarily affected ovary in 32 of these 149 cases (21.5%). Recurrence was significantly more frequent in patients <40 years (19.0% versus 10.1% 5-year recurrence rate, P < 0.001), usually in ovarian tissue, whereas disease-specific overall survival did not differ between the subgroups. In case of recurrent disease, malignant transformation was less frequent in younger than in older patients (12.0% versus 66.7%, P < 0.001), mostly presenting as invasive peritoneal carcinomatosis. Multivariate analysis for patients <40 years identified advanced International Federation of Gynecology and Obstetrics (FIGO) stage and fertility-sparing approach as independent prognostic factors negatively affecting progression-free survival (PFS) while, for patients ≥40 years, higher FIGO stage and incomplete staging was associated with impaired PFS. CONCLUSIONS: Despite favourable survival, young BOT patients with child-bearing potential are at higher risk for disease recurrence. However, relapses usually remain BOT in the preserved ovaries as opposed to older patients being at higher risk for malignant transformation in peritoneal or distant localisation. Therefore, fertility-sparing approach can be justified for younger patients after thorough consultation.

Women's mood at high altitude. sexual dimorphism in hypoxic stress modulation by the tryptophan-melatonin axis.

Sexual (and gender)-dimorphism in tolerance to hypobaric hypoxia increasingly matters for a differential surveillance of human activities at high altitude (HA). At low altitudes, the prevalence of anxiety and depression in women has already been found to double when compared with men; it could be expected to even increase on exposure to HA. In purposefully caring for the health of women at HA, the present work explores the potential involvement of the tryptophan (Trp)-melatonin axis in mood changes on exposure to hypobaric hypoxia. The present work highlights some already known anxiogenic effects of HA exposure. Hypoxia and insomnia reduce serotonin (5-HT) availability; the latter defect being expressed as failure of brown adipose tissue (BAT) activation and mood disorders. Rapid eye movement (REM) sleep organization and synapsis restoration that are additionally affected by hypoxia impair memory consolidation. Affective complaints may thus surge, evolving into anxiety and depression. Sex-related differences in neural network organization and hormonal changes during the menstrual cycle, and certainly also during the life cycle, underscore the possibility of 5-HT-related mood alterations, particularly in women on HA exposure. The mean brain rate of 5-HT synthesis at sea level is already 1.5-fold higher in males than in females. sexual dimorphism also evidences the overexpression effects of SERT, a 5-HT transporter protein. Gonadal and thyroid hormones, as influenced by HA exposure, further modulate 5-HT availability and its effects in women. Besides caring for adequate oxygenation and maintenance of one's body core temperature, special precautions concerning women sojourning at HA should include close observations of hormonal cycles and, perhaps, also trials with targeted antidepressants.

Anti-Müllerian hormone (AMH) levels in premenopausal breast cancer patients treated with taxane-based adjuvant chemotherapy - A translational research project of the SUCCESS A study.

BACKGROUND: Premenopausal women undergoing chemotherapy are at high risk for premature ovarian failure and its long-term consequences. Data on potential markers to evaluate ovarian reserve pre- and posttreatment are limited. Anti-Müllerian hormone (AMH) known for ovarian reserve in reproductive medicine could be a surrogate marker and was assessed in premenopausal breast cancer patients of the SUCCESS A study (EUDRA-CT no. 2005-000490-21). METHODS: We identified 170 premenopausal patients, age ≤ 40 years at trial entry, who received FEC-Doc as taxane-anthracylince based chemotherapy. Blood samples were taken at three time points: Before, four weeks after and two years after adjuvant chemotherapy. Serum AMH-levels were evaluated in a central laboratory by a quantitative immunoassay AMH Gen II ELISA (Beckman Coulter, Brea, USA). RESULTS: Median age was 36 years (21-40 years). Median serum AMH-level before chemotherapy was 1.37 ng/ml (range < 0.1-11.3 ng/ml). Four weeks after chemotherapy AMH-levels dropped in 98.6% of the patients to <0.1 ng/ml (range < 0.1-0.21 ng/ml). After two years, 73.3% (n = 101) showed no evidence of ovarian function recovery (AMH <0.1 ng/ml, range < 0.1-3.9 ng/ml). Permanent chemotherapy induced amenorrhea occurred only in 50.6% of the patients. CONCLUSIONS: In this analysis, premenopausal patients showed a high rate of ovarian impairment reflected by low AMH-levels after chemotherapy.
