Patterns of Recurrence and Clinical Outcome of Patients With Stage IIIC to Stage IV Epithelial Ovarian Cancer in Complete Response After Primary Debulking Surgery Plus Chemotherapy or Neoadjuvant Chemotherapy Followed by Interval Debulking Surgery: An Italian Multicenter Retrospective Study.

OBJECTIVE: The objective of this retrospective study was to assess the clinical outcome of patients with advanced epithelial ovarian cancer in complete response after primary debulking surgery (PDS) or neoadjuvant chemotherapy followed by interval debulking surgery (IDS]). METHODS: The authors reviewed the hospital records of 384 patients who underwent PDS (n = 322) or IDS (n = 62) and who were in complete response after primary treatment. RESULTS: Optimal (residual disease [RD] < 1 cm) and complete (no gross RD) cytoreduction rates were higher after IDS than after PDS (71.0% vs 55.9%; P = 0.001 and 51.6% vs 35.7%, respectively; P = 0.02). Tumor recurred in 73.0% of the 322 complete responders after PDS versus 87.1% of the 62 complete responders after IDS (P = 0.01). The IDS group showed a higher recurrence rate within 6 months (11.3% vs 3.1%: P = 0.01) and a trend to higher recurrence rate between 6 and 12 months (30.6% vs 19.9%). Tumor recurred in 57.4% of the 115 completely cytoreduced patients after PDS versus 87.5% of the 32 completely cytoreduced patients after IDS (P = 0.001). The IDS group showed a trend to higher recurrence rate within 6 months (6.2% vs 1.7%) and a higher recurrence rate between 6 and 12 months (37.5% vs 15.6%; P = 0.01). Two-year, 5-year, and 7-year progression-free survival were 65.8%, 40.8%, and 39.3% for completely cytoreduced patients after PDS versus 43.8%, 12.5%, and 12.5% for completely cytoreduced patients after IDS (P = 0.001); and 2-year, 5-year, and 7-year overall survival were 96.4%, 69.3%, and 50.4% for the former versus 87.1%, 41.8%, and 32.6% for the latter (P = 0.001). CONCLUSIONS: The clinical outcome of completely cytoreduced patients was significantly better for PDS group than for IDS group, and therefore, the achievement of no gross RD after surgery seemed to have a different prognostic relevance for the 2 groups.

Ovarian Cancer in Elderly Patients: Patterns of Care and Treatment Outcomes According to Age and Modified Frailty Index.

OBJECTIVE: The present study assessed the predictive value of age and Modified Frailty Index (mFI) on the management of primary epithelial ovarian cancer (EOC) patients aged 70 years or older (elderly). METHODS: A retrospective multicenter study selected elderly EOC patients treated between 2006 and 2014. Treatments were analyzed according to the following age group categories: (1) 70 to 75 years versus (2) older than 75 years, and mFI of less than 4 (low frailty) versus greater than or equal to 4 (high frailty). RESULTS: Seventy-eight patients were identified (40 in age group 1 and 38 in age group 2). The mFI was greater than or equal to 4 in 23 women. Median age of low frailty and high frailty was not significantly different (75.6 vs 75.3). Comorbidities were equally distributed according to age, whereas diabetes, hypertension, obesity, and chronic renal failure were more frequent in the high-frailty group. Performance status was different only according to mFI. Twenty percent of age group 1 versus 55.3% of age group 2 underwent none or only explorative surgical approach (P = 0.003), whereas surgical approaches were similar in the 2 frailty groups. The rate of postoperative complications was higher in high-frailty patients compared with low-frailty patients (23.5% vs 4.3%; P = 0.03). Chemotherapy was administered to all the patients, a monotherapy regimen to 50% of them. No differences in toxicity were registered, except more hospital recovery in the high-frailty cohort. Median survival time was in favor of younger patients (98 versus 30 months) and less-frailty patients (56 vs 27 months). CONCLUSIONS: Elderly EOC patients can receive an adequate treatment, but patients who are older than 75 years can be undertreated, if not adequately selected. The pretreatment assessment of frailty through mFI could be suggested in the surgical and medical management.

Clinical Outcomes of Stereotactic Body Radiotherapy in Oligometastatic Gynecological Cancer.

OBJECTIVE: The objective of this study was to assess the role of stereotactic body radiotherapy (SBRT) in the treatment of distantly recurrent, oligometastatic gynecological cancer. METHODS: The hospital records of 45 patients with F-fluorodeoxyglucose (F-FDG) positron emission tomography positive, distantly recurrent, oligometastatic gynecological cancer were reviewed. All these patients had a number of target lesions less than 5, with largest diameter less than 6 cm. The treatment was delivered with a TrueBeam LINAC and RapidArc technique, using 10 or 6 MV FFF beams. A total of 70 lesions were treated, and lymph nodes represented the most common site of metastases, followed by lung, liver, and soft tissues. Twenty lesions were treated with one single fraction of 24 Gy and 5 lesions received 27 Gy delivered in 3 fractions, depending on the ability to fulfill adequate target coverage and safe dose/volume constraints for the organ at risk with either regimen. RESULTS: Positron emission tomography scan 3 months after SBRT showed a complete response (CR) in 45 lesions (64.3%), a partial response in 14 (20.0%), a stable disease in 5 (7.1%), and a progressive disease in 6 (8.6%). No lesions in CR after SBRT subsequently progressed. Overall acute toxicity occurred in 13 (28.9%) patients. The most common grade 1 to 2 adverse event was pain (n = 9, 20.0%), followed by nausea and vomiting (n = 5, 11.1%). No grade 3 to 4 acute toxicities occurred, and no late toxicities were observed. Patients who failed to achieve a CR had a 2.37-fold higher risk of progression and a 3.60-fold higher risk of death compared with complete responders (P = 0.04 and P = 0.03, respectively). CONCLUSIONS: Stereotactic body radiotherapy offers an effective and safe approach for selected cases of oligometastatic gynecological cancer.

Novel insights on the malignant transformation of endometriosis into ovarian carcinoma.

The malignant transformation of endometriosis is an uncommon event, which happens in 0.7-2.5% of the cases, and, when occurs, it usually involves the ovary. A 2 to 3-fold higher risk of ovarian endometrioid and clear cell carcinoma has been reported in women with endometriosis. Pathological studies have detected a morphological continuum of sequential steps from normal endometriotic cyst epithelium to atypical endometriosis and finally to invasive carcinoma. Ovarian endometrioid carcinoma harbors mutations of CTNNB1 in 16-53.3%, of PTEN in 14-20% and of ARID1A in 30-55% of the cases. Ovarian clear cell carcinoma harbors mutations of PIK3CA in 20-40% and of ARID1 in 15-75% of the cases. Whereas estrogen receptors and progesterone receptors are quite always absent, HNF-1b is often over-expressed in this histotype. Atypical endometriosis and endometriosis-related ovarian neoplasms share molecular alterations, such as PTEN mutations, ARID1A mutations and up-regulation of HNF-1b. Moreover, ARID1A mutations have been noted in clear cell tumors and contiguous atypical endometriosis, but not in distant endometriotic lesions. The loss of BAF250a protein expression is suggestive for the presence of ARID1A mutations, and represents an useful marker of malignant transformation of endometriosis.

Menstrual function and childbearing potential after fertility-sparing surgery and platinum-based chemotherapy for malignant ovarian germ cell tumours.

Malignant ovarian germ cell tumours (MOGCT) account for 5% of all ovarian malignancies. Their elevated chemosensitivity, the frequent unilaterality and the young age of patients have strongly supported the conservative surgery as the standard approach, often followed by adjuvant platinum-based chemotherapy. The risk for recurrence is not affected by the performance of conservative versus radical surgery. During chemotherapy 50% of patients become amenorrhoeic but more than 95% of them resume normal menses after treatment completion. Literature has reported several healthy babies born after fertility-sparing surgery with or without chemotherapy for MOGCT. The incidence of miscarriages is in the normal range, whereas malformation rate is slightly higher compared to general population, without any difference between chemotherapy-treated and -untreated patients. Therefore, young women with MOGCT must be reassured of their excellent chances of survival and fertility preservation following conservative surgery and adjuvant platinum-based chemotherapy.

Fertility outcome of breast cancer and Hodgkin's lymphoma female survivors: a growing clinical challenge for gynecologists and oncologists.

The issue of taking into consideration future fertility in young women with breast cancer and Hodgkin's lymphoma [HL] will become more and more common and represent a growing clinical challenge for gynecologists and oncologists. The present paper will review literature data on the attempts of preventing chemotherapy-induced ovarian damage in these women and on their fertility outcome. Gonadotropin-releasing hormone [Gn-RH] agonists have been widely investigated as agents able to prevent ovarian failure in animal models and in humans. The majority of the studies on women with breast cancer and HL have shown a protective effect of Gn-RH agonists. A recent meta-analysis of five randomized trials, including 528 premenopausal breast cancer patients, revealed that relative risk [RR] of developing premature ovarian failure within one year was 0.40 (95% confidence interval [CI] = 0.21-0.75) for the women who received Gn-RH agonists with chemotherapy compared to those who received chemotherapy alone. However, the concurrent administration of Gn-RH agonists during chemotherapy appeared to have no effect on spontaneous pregnancy rates. Limited information are available about pregnancies in breast cancer and HL survivors, but the current literature appears to show no apparent increase in pregnancy complications, spontaneous abortions, or congenital abnormalities compared to general obstetric population.

Lymph-vascular space involvement and outer one-third myometrial invasion are strong predictors of distant haematogeneous failures in patients with stage I-II endometrioid-type endometrial cancer.

The aim of this retrospective study was to assess the predictive value of different clinicopathological variables (patient age, tumour size, FIGO grade, myometrial invasion, lymph-vascular space involvement [LVSI], invasion margins, peri-tumour phlogistic infiltrate and mitotic activity) for the risk of distant haematogenous recurrences in patients with endometrioid-type stage Ib-II endometrial cancer. Between August 1990 and April 2005, 259 patients had undergone laparotomy, peritoneal washing, total abdominal hysterectomy and bilateral salpingo-oophorectomy, with or without pelvic +/- para-aortic lymphadenectomy for endometrioid-type endometrial cancer. Thirty-six (13.9%) patients had developed recurrent disease after a median time of 17 months (range, 2-128 months). The relapse had been locoregional in 9, distant in 21 and both locoregional plus distant in 6 cases. This study assessed 12 patients with FIGO stage Ib-II disease who had developed distant haematogenous recurrences and 20 randomly chosen control patients with FIGO stage Ib-II disease who had remained recurrence-free after a median follow-up of 52 months (range, 37-66 months). Adjuvant therapy had been: no further treatment in 15 patients, external pelvic irradiation in 14 patients, adjuvant external pelvic irradiation plus brachytherapy in 2 patients and platinum-based chemotherapy followed by external pelvic irradiation in 1 patient. The site of distant failure had been the lung in 9 patients, liver in 2 patients and lung plus liver in 1 patient. A concomitant locoregional relapse (vagina or lymph nodes) had occurred in 3 patients. The median interval between surgery and the development of distant failure had been 16.5 months (range, 5-113 months). On univariate analysis, a higher incidence of FIGO grade 3 (50% versus 10%, p=0.0114), outer one-third myometrial invasion (91.7% versus 35.0%, p=0.0051) and LVSI (75.0.% versus 20.0%, p=0.0022) was found in the patients who had developed distant haematogeneous metastases compared to the recurrence-free women. Multivariate analysis showed that LVSI (p=0.0264) and deep myometrial invasion (p=0.0345) were independent predictive variables for the risk of distant haematogeneous failure. Patients with these pathological findings should be enrolled in randomised trials designed to assess the role of adjuvant chemotherapy alone or combined with sequential and/or concomitant external pelvic irradiation.

The fertility-sparing treatment in patients with endometrial atypical hyperplasia and early endometrial cancer: a debated therapeutic option.

Fertility-sparing treatment may represent a realist option for accurately selected young patients with endometrial atypical hyperplasia or well differentiated, early endometrial cancer. Oral progestins, and especially medroxyprogesterone acetate (MPA) and megestrol acetate with different doses and schedules, represent the most commonly used hormone agents in this clinical setting. Approximately three fourths of the women achieve a histologically documented complete response, with an mean response time of 12 weeks, but about one third of these subsequently developed a recurrence after a mean time of 20 months. The expression of receptor for progesterone receptor (PR), PTEN gene, DNA mismatch repair gene MLH1 and phospho-AKT on tissue specimens may be useful for selecting patients fit for a conservative management. Several successful pregnancies have occurred after a fertility-sparing treatment of endometrial atypical hyperplasia or endometrial cancer, more frequently with assisted reproductive technologies. The implementation of in vitro fertilisation techniques not only increases the chance of conception, but it may also decrease the interval to conception. The opportunity of a demolitive surgery after delivery or after childbearing being no longer required is a still debated issue. Large multicenter trials are strongly warranted to better define the selection criteria for a conservative treatment, endocrine regimen of choice, the optimal dosing, the duration of treatment and follow-up protocols. In any case, the patient should be accurately informed about the relatively high recurrence rates after complete response to hormone treatment and expectations for pregnancy.

The serum assay of tumour markers in the prognostic evaluation, treatment monitoring and follow-up of patients with cervical cancer: a review of the literature.

Pre-treatment serum squamous cell carcinoma antigen [SCC] levels are elevated in 28-88% of patients with squamous cell cervical cancer, and are related to tumour stage, tumour size, depth of stromal invasion, lymph-vascular space status, parametrial involvement and lymph node status. The clinical relevance of pre-treatment serum SCC assay is still debated. Some authors reported that it has no prognostic value, some others found that it is related to survival at univariate analysis, and some others detected that is an independent prognostic variable for survival. Serial SCC measurements reflect both the tumour response to treatment and the clinical outcome of patients. Increasing SCC levels can precede the clinical diagnosis of recurrent disease in 46-92% of the cases, with a mean lead time ranging from 2 to 8 months. According to some authors serum SCC assay during the follow-up does not improve the cure rate of patients who will ultimately develop a recurrence. However, it has been recently reported that the performance of a positron emission tomography [PET] in patients with asymptomatic SCC elevation can sometimes allow an earlier diagnosis of relapse with a survival benefit. SCC is a more sensitive serum tumour marker than CYFRA 21-1 for squamous cell cervical cancer in most series. Pre-treatment CA 125 levels are raised in 20-75% of patients with cervical adenocarcinoma, and reflect tumour stage, tumour size, histological grade, cervical stromal invasion, lymph-vascular space status and lymph node status. Elevated serum CA 125 has been also detected in patients with squamous cell cervical cancer, but with a positivity rate lower than that found in patients with cervical adenocarcinoma. Pre-treatment CA 125 levels appear to have a prognostic value, and rising serum CA 125 during follow-up may precede or be coincident with the clinical diagnosis of recurrent cervical adenocarcinoma. Serum levels of vascular endothelial growth factor [VEGF] are often elevated in patients with cervical cancer, and decrease significantly after successful treatment. However, the clinical relevance of serum VEGF assay is still investigational.

Molecular target therapies in endometrial cancer: from the basic research to the clinic.

Molecular targeted therapies represent an interesting field of pharmacological research in endometrial cancer. The loss of PTEN (phosphatase and tensin homolog deleted on chromosome 10) function, with consequent activation of the PI3K (phosphatidylinositol-3-kinase)-AKT (serine/threonine-specific protein kinase)-mTOR (mammalian target of rapamycin) signaling pathway, occurs in 32-83% of endometrioid-type endometrial carcinomas, thus suggesting a role for mTOR inhibition in this malignancy. Some analogues of rapamycin (CCI-799, RAD-001, AP-23573) have been developed and tested in different tumors including endometrioid-type endometrial carcinoma. For example, AP-23573 achieved a clinical benefit response in 33% of 27 heavily pretreated patients, and CCI-799 obtained a 26% partial response rate and a 63% stable disease rate in 19 patients. Overexpression of ErbB-2 (epidermal growth factor type II receptor) has been detected in 18-80% of uterine papillary serous carcinomas (UPSCs), thus providing a biological rationale for the use of trastuzumab in these aggressive tumors. UPSC often overexpresses claudin-3 and claudin-4, which represent the epithelial receptors for Clostridium perfringens enterotoxin (CPE). CPE-mediated therapy might be a novel treatment modality for UPSC resistant to chemotherapy. A better understanding of the signaling transduction pathways that are dysregulated in endometrioid-type endometrial carcinoma and UPSC will allow the development of novel molecular targeted therapies.

Brain recurrences in patients with ovarian cancer: report of 12 cases and review of the literature.

The aim of the investigation was to assess 12 cases of brain recurrences among ovarian cancer patients who had undergone surgery followed by platinum-based chemotherapy. Brain lesions were the first recurrence in 4 (33%) patients, the second recurrence in 7 (58%), and the fourth recurrence in one patient. The median time from ovarian cancer diagnosis to brain metastasis detection was 33.5 months (range, 13.5-86.5 months), brain metastases were multiple in 6 (50%) cases, and extra-cranial disease was present in 7 (58%) cases. Brain recurrence was symptomatic in 10 patients and the clinical presentation included impaired deambulation, extremity weakness, seizure, headache, nausea/vomiting and visual disturbance. Out of the 6 patients with single brain metastases, one underwent surgery, one had surgical excision followed by whole brain irradiation, 3 patients received stereotactic radiotherapy (followed by chemotherapy for coexistent extra-abdominal recurrence in one), and one had only symptomatic treatment. Out of the 6 patients with multiple brain metastases, four received whole brain irradiation (followed by chemotherapy for concomitant extra-cranial recurrence in one case), one patient had gamma-knife irradiation of three cerebral lesions (followed by chemotherapy for concurrent abdominal recurrence), and one patient had only symptomatic treatment. The median overall survival from diagnosis of brain metastasis was 8.3 months (range, 1-28 months), and it was not related to the number of brain metastases (multiple versus single), presence or absence of extra-cranial disease, or interval between ovarian cancer diagnosis and brain metastasis detection (<33.5 months versus > or =33.5 months). In conclusion, brain metastasis from ovarian cancer can represent a late manifestation of the disease, associated with a very poor prognosis.

Dose-dense Paclitaxel- and Carboplatin-based Neoadjuvant Chemotherapy Followed by Surgery or Concurrent Chemo-radiotherapy in Cervical Cancer: a Preliminary Analysis.

AIM: To assess preliminary results with dose-dense neoadjuvant chemotherapy (NACT) prior to surgery or concurrent chemo-radiotherapy (CCRT) in cervical cancer. PATIENTS AND METHODS: Thirty patients received weekly paclitaxel (80 mg/m2) plus carboplatin (AUC2) for 6 cycles followed by radical hysterectomy in 16 (stage Ib2-IIb), conisation in one (stage Ib1), and CCRT in 13 (stage Ib2-IIb). Median follow-up of survivors was 12 months (range=3-22). RESULTS: Among the surgically treated patients, clinical overall response rate (RR) was 82.3%, optimal pathological RR was 17.6%, and suboptimal pathological RR with intra-cervical residual disease was 41.2%. Only one patient relapsed. Among the CCRT treated patients, partial RR after NACT was 76.9% and complete RR after CCRT was 58.3%. However, 42.8% of complete responders recurred. Toxicity was acceptable. CONCLUSION: Dose-dense NACT seems to achieve promising RRs with manageable toxicity in cervical cancer. Investigation on larger series with longer follow-up is warranted.

Metformin use and gynecological cancers: A novel treatment option emerging from drug repositioning.

Metformin exerts antitumor effects mainly through AMP-activated protein kinase [AMPK] activation and phosphatidylinositol 3-kinase [PI3K]-Akt-mammalian target of rapamycin [mTOR] inhibition. This drug leads to activation of the cellular energy-sensing liver kinase B1 [LKB1]/AMPK pathway. LKB1 is implicated as a tumor suppressor gene in molecular pathogenesis of different malignancies. AMPK is a serine/threonine protein kinase that acts as an ultra-sensitive cellular energy sensor maintaining the energy balance within the cell. AMPK activation inhibits mRNA translation and proliferation in cancer cells via down-regulation of PI3K/Akt/mTOR pathway. Moreover, metformin decreases the production of insulin, insulin-like growth factor, inflammatory cytokines and vascular endothelial growth factor, and therefore it exerts anti-mitotic, anti-inflammatory and anti-angiogenetic effects. Recent in vitro and experimental data suggest that metformin electively targets cancer stem cells, and acts together with chemotherapy to block tumor growth in different cancers. Several epidemiological studies and meta-analysis have shown that metformin use is associated with decreased cancer risk and/or reduced cancer mortality for different malignancies. The present review analyzes the recent biological and clinical data suggesting a possible growth-static effect of metformin also in gynecological cancers. The large majority of available clinical data on the anti-cancer potential of metformin are based on observational studies. Therefore long-term phase II-III clinical trials are strongly warranted to further investigate metformin activity in gynecological cancers.

Concomitant External-beam Irradiation and Chemotherapy Followed by High-dose Rate Brachytherapy Boost in the Treatment of Squamous Cell Carcinoma of the Vagina: A Single-Center Retrospective Study.

AIM: To assess the outcome of 35 patients with vaginal carcinoma treated with different radiotherapy modalities. MATERIALS AND METHODS: Thirty-one patients received external-beam irradiation (EBRT) to the entire vagina, para-vaginal area and pelvic nodes (total dose=45-50.4 Gy). Concomitant chemotherapy was used in 22 patients. Nineteen patients received additional 15-25 Gy high-dose-rate brachytherapy (BT) boost and eight received additional EBRT boost to the primary tumor site. Four women received exclusive 30-40 Gy high-dose-rate BT. RESULTS: Median progression-free survival and median overall survival were 22 months and 89 months, respectively. Age <70 years, use of EBRT plus BT, and concomitant chemotherapy were associated with better progression-free (p=0.002, p=0.007, and p=0.02) and overall (p=0.01, p=0.009, p=0.009) survival. CONCLUSION: Concomitant EBRT and chemotherapy followed by BT is the best treatment for vaginal carcinoma.

Radiotherapy as Definitive Treatment of Patients with Primary Vulvar Carcinoma Unfit for Surgery and with Recurrent Vulvar Carcinoma After Primary Radical Surgery: Results of a Retrospective Single-center Study.

AIM: To assess the outcome of patients with vulvar carcinoma unfit for surgery treated with radiotherapy for primary disease and for those with recurrent disease after primary surgery. PATIENTS AND METHODS: The study was conducted on 16 patients with primary disease and 31 with recurrent disease. RESULTS: An objective response and long-term control were obtained in 43.8% and 18.8% of patients with primary carcinoma. Median survival after primary radiotherapy was 15 months. An objective response and long-term control were achieved in 100% and 20% of the 15 patients with local recurrence. Only two out of the 13 patients with groin recurrence were recovered by salvage treatment, and all three patients with distant recurrence died of their disease. Median survival after relapse in the 31 patients was 33 months. CONCLUSION: Radiotherapy achieves unsatisfactory results in patients with primary vulvar carcinoma who are unfit for surgery as well as in those with recurrent disease after surgery.

Prognosis of Patients with Gestational Trophoblastic Neoplasia and Obstetric Outcomes of Those Conceiving After Chemotherapy.

AIM: To assess prognosis of gestational trophoblastic neoplasia (GTN) and obstetric outcome after chemotherapy. PATIENTS AND METHODS: Sixty-six patients had diagnosis of hydatiform mole on curettage and 18 developed GTN. Two patients were referred with pathological diagnosis of GTN. Chemotherapy was tailored according to International Federation of Gynecology and Obstetrics risk scoring system. RESULTS: All patients with GTN but one, were recovered by chemotherapy and had no evidence of disease after a median follow-up of 80 months. Only the patient with epithelioid trophoblastic tumor died of disease. Seven out of the eight women who tried to conceive after chemotherapy became pregnant. Ten conceptions occurred, resulting in no molar pregnancy, three miscarriages and seven term-live healthy births (70.0%). All seven babies showed normal development and growth after a median follow-up of 38 months. CONCLUSION: The prognosis of women with GTN is very good, and obstetric outcomes of those who conceive after chemotherapy are similar to those of the general population.

Acute and late vaginal toxicity after adjuvant high-dose-rate vaginal brachytherapy in patients with intermediate risk endometrial cancer: is local therapy with hyaluronic acid of clinical benefit?

PURPOSE: The aim of the present study was to evaluate the effectiveness of hyaluronic acid (HA) in the prevention of acute and late vaginal toxicities after high-dose-rate (HDR) vaginal brachytherapy (BT). MATERIAL AND METHODS: Between January 2011 and January 2015, we retrospectively analyzed 126 patients with endometrial cancer who underwent extrafascial hysterectomy with or without lymphadenectomy and adjuvant HDR-vaginal BT +/- adjuvant chemotherapy. The total dose prescription was 21 Gy in 3 fractions (one fraction for week). Vaginal ovules containing 5 mg of HA were given for whole duration of vaginal BT and for the two following weeks. Acute and late toxicities were evaluated according to CTCAE vs 4.02. RESULTS: According to the revised FIGO 2009 classification, most tumors were in stage IA (30.9%) and in stage IB (57.9%). Thirty-three patients (26.2%) received adjuvant chemotherapy before vaginal BT. Five-year disease-free survival (DFS) and five-year overall survival (OS) were 88% and 93%, respectively. The most common grade 1-2 acute toxicities were vaginal inflammation (18 patients, 14.3%) and dyspareunia (7 patients, 5.5%). Two patients (1.6%) had more than one toxicity. Late toxicity occurred in 20 patients (15.9%). Grade 1-2 late toxicities were fibrosis (14 patients, 11.1%) and telangiectasias (7 patients, 5.5%). Six patients (4.8%) had more than one late toxicity. No grade 3 or higher acute or late toxicities were observed. CONCLUSIONS: These results appear to suggest that the local therapy with HA is of clinical benefit for intermediate risk endometrial cancer patients who receive adjuvant HDR-vaginal BT after surgery. A randomized trial comparing HA treatment vs. no local treatment in this clinical setting is warranted to further evaluate the efficacy of HA in preventing vaginal BT-related vaginal toxicity.

Clinico-pathological and biological prognostic variables in squamous cell carcinoma of the vulva.

Several clinical-pathological parameters have been related to survival of patients with invasive squamous cell carcinoma of the vulva, whereas few studies have investigated the ability of biological variables to predict the clinical outcome of these patients. The present paper reviews the literature data on the prognostic relevance of lymph node-related parameters, primary tumor-related parameters, FIGO stage, blood variables, and tissue biological variables. Regarding these latter, the paper takes into account the analysis of DNA content, cell cycle-regulatory proteins, apoptosis-related proteins, epidermal growth factor receptor [EGFR], and proteins that are involved in tumor invasiveness, metastasis and angiogenesis. At present, the lymph node status and FIGO stage according to the new 2009 classification system are the main predictors for vulvar squamous cell carcinoma, whereas biological variables do not have yet a clinical relevance and their role is still investigational.

Treatment options in recurrent cervical cancer (Review).

The management of recurrent cervical cancer depends mainly on previous treatment and on the site and extent of recurrence. Concurrent cisplatin-based chemo-radiation is the treatment of choice for patients with pelvic failure after radical hysterectomy alone. However, the safe delivery of high doses of radiotherapy is much more difficult in this clinical setting compared with primary radiotherapy. Pelvic exenteration usually represents the only therapeutic approach with curative intent for women with central pelvic relapse who have previously received irradiation. In a recent series, the 5-year overall survival and operative mortality after pelvic exenteration ranged from 21 to 61% and from 1 to 10%, respectively. Free surgical margins, negative lymph nodes, small tumour size and long disease-free interval were associated with a more favourable prognosis. Currently, pelvic reconstructive procedures (continent urinary conduit, low colorectal anastomosis, vaginal reconstruction with myocutaneous flaps) are strongly recommended after exenteration. Concurrent cisplatin-based chemo-radiation is the treatment of choice for isolated para-aortic lymph node failure, with satisfactory chances of a cure in asymptomatic patients. Chemotherapy is administered with palliative intent to women with distant or loco-regional recurrences not amenable by surgery or radiotherapy. Cisplatin is the most widely used drug, with a response rate of 17-38% and a median overall survival of 6.1-7.1 months. Cisplatin-based combination chemotherapy achieves higher response rates (22-68%) when compared with single-agent cisplatin, but median overall survival is usually less than one year. In a recent Gynecologic Oncology Group (GOG) trial the combination topotecan + cisplatin obtained a significantly longer overall survival than single-agent cisplatin in patients with metastatic or recurrent or persistent cervical cancer. A subsequent GOG study showed a trend in terms of longer overall survival and better quality of life for the doublet cisplatin + paclitaxel vs. the doublets cisplatin + topotecan, cisplatin + vinorelbine, and cisplatin + gemcitabine. Molecularly targeted therapy may represent a novel therapeutic tool, but its use alone or in combination with chemotherapy is still investigational.

Clinicopathological variables predictive of clinical outcome in patients with FIGO stage Ib2-IIb cervical cancer treated with cisplatin-based neoadjuvant chemotherapy followed by radical hysterectomy.

The aim of this retrospective investigation was to assess the prognostic relevance of some pre-treatment clinical variables and histological findings assessed on the surgical samples of 46 patients with stage Ib(2)-IIb cervical cancer treated with cisplatin-based neoadjuvant chemotherapy followed by radical hysterectomy. Seven patients achieved a pathologically documented complete response, 6 had an optimal partial response, 29 had a suboptimal partial response, and 4 had stable disease. As for histological findings on surgical samples, 7 (15.2%) patients had positive lymph nodes, 10 (21.7%) had lymph-vascular space involvement, and 10 (21.7%) had positive parametria and/ or surgical margins. After surgery, 38 patients received further treatment with chemotherapy and/or irradiation. The median follow-up of survivors was 53 months (range, 4-167 months).Thirteen (28.3%) patients developed recurrent tumour, 11 (23.9%) patients died of tumour and one patient died of ictus with no clinical evidence of tumour. Recurrence-free and overall survival were significantly related to tumour stage (Ib(2)-IIa versus IIb, p=0.01 and p=0.02, respectively), pathologically assessed lymph node status (negative versus positive, p=0.0009 and p=0.007), lymph-vascular space status (negative versus positive, p=0.01 and p=0.009), parametrial and/or surgical margin status (negative versus positive, p=0.0001 and p=0.0005), but not to haemoglobin level before chemotherapy, patient age, tumour grade or chemotherapy regimen. A platelet count before chemotherapy above the median value of 272,000/microl was associated with a trend for a shorter recurrence-free survival (p=0.06) and with a significantly shorter overall survival (p=0.04) when compared with a lower platelet count. In conclusion, FIGO stage, lymph node status, lymph-vascular space status, parametrial and/or surgical margin status and pre-treatment platelet count are predictors of clinical outcome in patients with FIGO stage Ib(2)-IIb cervical cancer undergoing cisplatin-based neoadjuvant chemotherapy followed by radical hysterectomy. A multivariate analysis on a larger series of homogeneously treated patients is warranted to better define the clinicopathological risk factors useful to adequately plan the therapeutic strategy.
