Uterine Sarcoma Treated by Cytoreductive Surgery and Intraperitoneal Hyperthermic Perfusion: a Feasiblity Study

The purpose of this study was to evaluate the feasibility and the outcome impact of cytoreductive surgery (CRS) followed by intraperitoneal hyperthermic perfusion (IPHP) in patients affected by uterine sarcoma (US). Ten US patients were treated with CRS+IPHP (closed technique, cisplatin+mitomycin C or cisplatin+doxorubicin). Median follow-up was 25 months (range: 2-61). Five patients received preoperative chemotherapy. Nine cases underwent optimal CRS. Five-year overall and progression-free survivals were 65% and 30%, respectively. There was no operative morbidity, nor mortality and nor toxicity. Six patients presented disease progression. CRS+IPHP proved feasible and safe, with encouraging outcome results, warranting confirmation by further prospective controlled trials.

Is aortic lymphadenectomy indicated in locally advanced cervical cancer after neoadjuvant chemotherapy followed by radical surgery? A retrospective study on 261 women

OBJECTIVES

The aim of this study was to estimate the rate of aortic lymph nodes (LN) metastases/recurrences among patients affected by locally advanced stage cancer patients (LACC), treated with neoadjuvant chemotherapy (NACT) and radical surgery.

METHODS

Retrospective evaluation of consecutive 261 patients affected by LACC (stage IB2-IIB), treated with NACT followed by radical surgery at National Cancer Institute, Milan, Italy, between 1990 and 2011.

RESULTS

Stage at presentation included stage IB2, IIA and IIB in 100 (38.3%), 50 (19.2%) and 111 (42.5%) patients, respectively. Squamous cell carcinoma accounted for more than 80%, followed by adenocarcinoma or adenosquamous cancers (20%). Overall, 56 women (21.5%) had LN metastases. Four out of 83 women (5%) who underwent both pelvic and aortic LN dissection had aortic LN metastases, and all women had concomitant pelvic and aortic LN metastases. Only one woman out of 178 (0.5%) who underwent pelvic lymphadenectomy only, had an aortic LN recurrence. Overall 2% of women (5/261) had aortic LN metastases/recurrence.

CONCLUSIONS

Our data suggest that aortic lymphadenectomy at the time of surgery is not routinely indicated in LACC after NACT, but should reserved in case of bulky LN in both pelvic and/or aortic area. The risk of isolated aortic LN relapse is negligible. Further prospective studies are warranted.

Prospective phase II trial of trabectedin in BRCA-mutated and/or BRCAness phenotype recurrent ovarian cancer patients: the MITO 15 trial

BACKGROUND

Current evidence suggest that trabectedin is particularly effective in cells lacking functional homologous recombination repair mechanisms. A prospective phase II trial was designed to evaluate the activity of trabectedin in the treatment of recurrent ovarian cancer patients presenting BRCA mutation and/or BRCAness phenotype.

PATIENTS AND METHODS

A total of 100 patients with recurrent BRCA-mutated ovarian cancer and/or BRCAness phenotype (≥2 previous responses to platinum) were treated with trabectedin 1.3 mg/mq i.v. q 3 weeks. The activity of the drug with respect to BRCA mutational status and to a series of polymorphisms [single-nucleotide polymorphisms (SNPs)] involved in DNA gene repair was analyzed.

RESULTS

Ninety-four were evaluable for response; in the whole population, 4 complete and 33 partial responses were registered for an overall response rate (ORR) of 39.4. In the platinum-resistant (PR) and -sensitive (PS) population, an ORR of 31.2% and 47.8%, and an overall clinical benefit of 54.2% and 73.9%, respectively, were registered. In the whole series, the median progression-free survival (PFS) was 18 weeks and the median overall survival (OS) was 72 weeks; PS patients showed a more favorable PFS and OS compared with PR patients. BRCA gene mutational status was available in 69 patients. There was no difference in ORR, PFS and OS according to BRCA 1-2 status nor any association between SNPs of genes involved in DNA repair and NER machinery and response to trabectedin was reported.

CONCLUSIONS

Our data prospectively confirmed that the signature of 'repeated platinum sensitivity' identifies patients highly responsive to trabectedin. In this setting, the activity of trabectedin seems comparable to what could be obtained using platinum compounds and the drug may represent a valuable alternative option in patients who present contraindication to receive platinum.

The role of secondary surgery in recurrent ovarian cancer

Despite optimal treatment (complete cytoreduction and adjuvant chemotherapy), 5-year survival for advanced ovarian cancer is approximately 30% and most patients succumb to their disease. Cytoreductive surgery is accepted as a major treatment of primary ovarian cancer but its role in recurrent disease is controversial and remains a field of discussion mainly owing to missing data from prospective randomized trials. A critical review of literature evidence on secondary surgery in recurrent ovarian cancer will be described.

Risk factors for type 2 diabetes in women attending menopause clinics in Italy: a cross-sectional study

OBJECTIVE

To analyze risk factors for type 2 diabetes among women attending menopause clinics in Italy for counselling about the menopause.

SUBJECTS

Women attending a network of first-level outpatient menopause clinics in Italy for general counselling about menopause or treatment of menopausal symptoms.

METHODS

Cross-sectional study with no exclusion criteria. Type 2 diabetes was defined according to National Diabetes Data Groups Indications and the fasting blood glucose at an oral glucose tolerance test within the previous year.

RESULTS

Out of the 44 694 considered in this analysis, 808 had a diagnosis of diabetes type 2 (1.8%). In comparison with women aged < 50 years, the multivariate odds ratios (OR) of type 2 diabetes were 1.31 (95% confidence interval (CI), 0.99-1.74) for women aged 50-52 years, 1.66 (95% CI, 1.27-2.17) at 53-56 years and 2.84 (95% CI, 2.20-3.67) in women aged > or = 57 years. Type 2 diabetes was less frequently reported in more educated women (OR high school/university vs. primary school = 0.44 (95% CI, 0.36-0.55)). Being overweight was associated with an increased risk of type 2 diabetes. In comparison with women reporting a low level of physical activity, the multivariate OR of type 2 diabetes was 0.67 (95% CI, 0.54-0.84) for women reporting regular physical activity. In comparison with premenopausal women, the multivariate OR of type 2 diabetes was 1.38 (95% CI, 1.03-1.84) in women with natural menopause. This finding was present also after allowing for the potential confounding effect of age. The multivariate OR of diabetes for users of hormonal replacement therapy was 0.58 (95% CI, 0.46-0.73).

CONCLUSIONS

This large cross-sectional study suggests that postmenopausal women are at higher risk of type 2 diabetes after allowance for the effect of age. Other main determinants of risk of type 2 diabetes in women around menopause were low socioeconomic status and being overweight. Diabetes was found less frequently in those taking hormone replacement therapy.

Role of trabectedin (T) in the management of advanced uterine leiomyosarcoma (U-LM)

10530

Background: To explore the clinical impact of T in U-LM. T has been approved in Europe for second line treatment of advanced soft tissue sarcomas (STS). Efficacy is well established in liposarcoma and leiomyosarcoma. U-LMs display peculiar clinical and genetic features compared to other STS. These differences may be responsible for the sensitivity of this subtype to therapy, thus justifying an evaluation of the activity of T in a relatively homogeneous series of U-LM patients. Methods: From April 2000, 56 patients (pts) with advanced disease, previously exposed to a median of 3 chemotherapy lines (range 1–5), received T within an expanded access programme at two European referral institutions for sarcoma. The clinical records were reviewed focusing on response and treatment outcome. Two pts were excluded from the analysis having received only 1 course of T. Median age was 56 yrs (range 29–73), median number of metastatic sites was 2 (range 1–4), the most frequent metastatic site was lung (88%), 24 patients had a local relapse. Results: A total of 252 courses were delivered (median 3, IQR2–6) and 36% of patients received more than 5 courses of T. Fifty-two patients were evaluable for response. A partial response was observed in 11 patients and stable disease in 15, for a PR rate of 21% and a tumor control rate of 50%. The median progression-free survival was 3.6 months (CI95% 2.6–6.7), with 41% of patients free from progression at 6 months. Conclusions: These results compare favourably with other systemic treatments in advanced U-LMS and support their sensitivity to T. This should prompt further studies to prospectively evaluate the efficacy of T in U-LMS and elucidate possible biological predictive factors (e.g. DNA repair protein expression).

Could follow-up different modalities play a role in asymptomatic cervical cancer relapses diagnosis?

OBJECTIVE

The aim of this study was to evaluate how much clinical surveillance performed by follow-up scheduled appointments may correctly identify asymptomatic recurrences and describe the pattern of relapse detected by procedures.

METHODS

The records of 327 consecutive women with recurrent cervical cancer treated from 1980 to 2005 were retrospectively collected in 8 Italian Institutions. Primary disease and recurrence data were picked up: diagnosis, type of treatment, FIGO stage, tumour grade, histology, clinical lesion size, number of localizations and site of relapse, presence of symptoms and primary method of detection, the type of treatment of recurrence and follow-up data, such as appointment date, clinical status and procedure performed. A multivariate analysis was carried out using the Cox proportional hazards regression model. Survival curves were calculated using the Kaplan-Meier technique. Survival differences were evaluated by the log-rank test.

RESULTS

Sixty-seven out of 327 patients (20.5%) had a local recurrence on vaginal vault, 120 (36.7%) in central pelvis, 31 (9.5%) in pelvic wall, 16 cases (4.9%) in lymph nodes. Seventy-nine patients (24.2%) showed a distant relapse while 14 (4.3%) developed both a distant and local relapse. Among patients with distant relapses 39 (49.4%) had lung metastasis, 41 (51.9%) an hepatic recurrence, 4 (5.1%) a bone relapse. Among distant sites 32 out of 79 patients (40.5%) had single relapse and 46 (58.2%) had multiple localizations. The site of relapse influenced survival since patients with vaginal vault recurrences lived significantly longer than patients with recurrences in other sites. Ninety-seven (29.7%) patients were symptomatic and anticipated the scheduled visit, 66 (20.2%) reported their symptoms during the follow-up visit and 164 (50.1%) were asymptomatic and the diagnostic path was introduced by a planned visit or exam. Between asymptomatic patients the first procedure was clinical visit for 85 patients out of 164 patients (51.8%), imaging for 60 patients (36.6%), both clinical visit and imaging for 14 (8.5%) and cytology for 5 (3%, Pap smear test). The median OS of symptomatic patients was 37 months versus 109 months of asymptomatic patients (Log rank, p=0.00001). The median survival since recurrence was 9 months for symptomatic patients and median was not reached for asymptomatic patients (p<0.0001). The median disease-free interval was 24 months for asymptomatic patients vs. 36 months for symptomatic patients (p=0.03).

CONCLUSIONS

Our study helps demonstrate the great need of prospective cost-effectiveness studies which are lacking at the present time.
