RESUMO

Oral mucosa pigmentations belong to a heterogeneous variety of lesions, which are usually divided into two groups: exogenous or endogenous pigmentations. The pigmented lesions most frequently found in the oral mucosa are the amalgam tattoo, the melanotic macula and the nevus. All these lesions may affect every part of the oral mucosa, and they may represent a hard diagnostic challenge for the clinician; the clinical objective examination is not sufficient to make a correct diagnosis. Reflectance Confocal Microscopy provides a real-time microscopic evaluation of tissue layers, and is widely considered a useful auxiliary tool in monitoring skin and mucosa lesions. In this context, Reflectance Confocal Microscopy imaging is a valid aid in the management of oral mucosa pigmented lesions, to corroborate and support the diagnostic process.

RESUMO

BACKGROUND: Neoadjuvant chemotherapy (NACT) has been recognized as a reliable therapeutic strategy in patients with unresectable advanced epithelial ovarian cancer (EOC). The molecular events leading to platinum (Pt) response in NACT settings have hitherto not been explored. In the present work, longitudinal changes of miRNA expression profile were investigated to identify miRNA families with prognostic role in high-grade serous EOC patients who received the NACT regimen. PATIENTS AND METHODS: One hundred sixty-four matched tumor biopsies taken at initial laparoscopic evaluation and at interval-debulking surgery (IDS) after four courses of Pt-based therapy were selected from 82 stage IIIC-IV high-grade serous-EOC patients that were judged unsuitable for complete primary debulking and subjected the NACT protocol. miRNA profiling by microarray, real-time PCR and immuno-histochemical staining for Smad2 phosphorylation (P-Smad2) were used for data analysis. RESULTS: Analysis revealed that 369 miRNAs were differentially expressed in matched biopsies (referred to as DEMs). DEMs were not scattered across the genome, but clustered into families: miR-199, let-7, miR-30, miR-181 and miR-29. Multivariate analysis showed that miR-199a-3p, miR-199a-5p, miR-181a-5p and let-7g-5p associated with overall and progression-free survival (P < 0.05); miR-199a-3p, miR-199a-5p and miR-181a-5p associated with residual tumor volume and Pt-free interval (P < 0.05). Immuno-histochemical staining confirmed an enrichment of P-Smad2, a marker of transforming growth factor-ß activation, in tumors from patients with shorter PFS and OS, and with high levels of expression of miR-181a-5p (P < 0.05). Kaplan-Meier curves plotting concomitant expression of P-Smad2 and miR-181a-5p show significant differences in PFS and OS compared with those depicting the expression of each biomarker alone (P < 0.001). CONCLUSIONS: This study describes several miRNA families with a prognostic role in the NACT setting. It also confirms that concomitant analysis of P-Smad2 and miR-181a-5p in surgical samples may be capable of identifying those ovarian cancer patients with poor outcome and little chance of response to Pt-based NACT.

RESUMO

BACKGROUND: To analyze the 5- and 7-year survival outcomes for women with platinum-sensitive recurrent epithelial ovarian cancer (REOC) who underwent secondary cytoreductive surgery (SCS) plus platinum-based hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: From the electronic databases of the Department of Obstetrics and Gynecology at the Catholic University of the Sacred Heart of Rome and of the S. Orsola Hospital, University of Bologna, a consecutive series of REOC patients were selected using the following inclusion criteria: primary platinum-free interval (PFI-1) of 6 months or longer, completeness of secondary cytoreduction score (CC) of 1 or lower, minimum follow-up period of 48 months, Eastern Cooperative Group (ECOG) performance status at recurrence of 1 or less, and platinum-based HIPEC. Progression-free survival (PFS) and post-relapse survival (PRS) were calculated as the time between SCS + HIPEC and secondary recurrence or death, respectively. RESULTS: The final study population included 70 women with platinum-sensitive REOC. The median follow-up time was 73 months (range 48-128 months), and the median PFI-1 was 19 months (range 6-100 months). At the time of recurrence, the median peritoneal cancer index was 7 (range 1-21), and a CC score of 0 was achieved for 62 patients (88.6 %). As the HIPEC drug, we used oxaliplatin in 17 cases (38.6 %) and cisplatin in 43 cases (61.4 %). No postoperative deaths were observed, and the complication rate for grades 3 and 4 disease was 8.6 %. The median PFS duration was 27 months (range 5-104 months), and the 5- and 7-year PRS rates were respectively 52.8 and 44.7 %, (median PRS 63 months). CONCLUSIONS: The current study demonstrated favorable 5- and 7-year PRS rates for platinum-sensitive REOC patients undergoing SCS + HIPEC, which encourages the inclusion of patients in randomized clinical trials for definitive conclusions to be drawn.

RESUMO

OBJECTIVE: As a result of relevant achievements in the field of translational research, several active drugs and multiple biological targets are available in ovarian cancer (OC). In this complex scenario, there is an urgent need to effectively summarize the available data in order to update conclusions, and outline perspectives. METHODS: The results in terms of target identification and drug development have been summarized using the well-known hallmarks of cancer firstly described, and recently modified by Hanahan and Weinberg [1-2]. Published data from clinical trials have been retrieved from PubMed, Embase, CINAHL and Cochrane database. Ongoing clinical trials were searched using clinicaltrials.gov web platform, and identified using NCT number. RESULTS: Genomic instability and angiogenesis are the most actively investigated hallmarks in high-grade serous OC, and the inhibition of tumor immune evasion appears as the emerging strategy for molecularly-driven therapy. Targeting sustained proliferative signaling through MEK and mTOR inhibitors seems the most promising approach in clear cell, and low-grade serous OC. CONCLUSIONS: This substantial amount of data suggests that targeted therapies are already part of the clinical and therapeutic management of OC patients. The expectations of getting from translational research a better knowledge of tumor biology and therefore personalized drugs are high and worthy of maximum effort from referral centers.

RESUMO

OBJECTIVE: To evaluate the timing and pattern of relapse, and duration of response to second line chemotherapy in advanced ovarian cancer (AOC) patients treated with first line carboplatin-paclitaxel chemotherapy with or without bevacizumab. PATIENTS AND METHODS: This is a case-control study including 222 AOC patients. Seventy-four women treated with first line carboplatin-paclitaxel-bevacizumab chemotherapy (Cases) were matched based on laparoscopic predictive index value, and residual tumor at first surgery with 148 AOC patients treated with carboplatin-paclitaxel. Distribution of pattern of relapse, and response to second line chemotherapy was compared between the two groups. Time to Progression (TTP) for second line chemotherapy was also analyzed for study purpose. RESULTS: Median platinum-free interval (PFI) was 16months (range 2-65) in Cases, compared with 9months (1-83) in Controls (p-value=0.001). Twenty patients (51.3%) among Cases showed recurrence in multiple anatomic sites, compared with 31 (31.9%) in the Control group (p-value=0.035). Peritoneal recurrence occurred as diffuse in 30 Cases (96.8%), and 60 Controls (82.2%; p-value=0.046). Secondary cytoreductive surgery (SCS) was successfully completed in 53.5% of Controls compared to 10.0% of Cases (p-value=0.016). In women with fully platinum-sensitive relapse, response rate to second line chemotherapy was 85.2% in Controls, compared to 38.4% in Cases (p-value=0.002). Finally, Cases showed a shorter TTP, compared to Controls (5months vs 8months; p-value=0.041). CONCLUSIONS: Incorporation of bevacizumab into upfront regimens prolongs PFI in AOC patients, but is associated with wider presentation of relapse, lower rate of complete SCS, and shorter TTP to second line chemotherapy in women with platinum-sensitive disease.

RESUMO

OBJECTIVE: To further investigate the role of MIS comparing patients submitted to MI-IDS with a balanced population treated by standard laparotomy. METHODS: The investigational arm (Cases) includes 30 AEOC patients treated with MI-IDS. The Control arm included a consecutive series of 65 AEOC patients submitted to laparotomic IDS. Inclusion criteria were: age>18years, histologically proven EOC, clinical complete/partial response after NACT, and ECOG PS <2. Preoperative clinical data, perioperative and oncological outcomes were analyzed. General Well-Being Schedule (GWBS) was administered to evaluate quality of life before and after surgery. RESULTS: Both groups were well-balanced. A higher percentage of women among Cases received bevacizumab-containing NACT compared with Controls. No statistical differences were registered in terms of surgical procedures and residual tumor. A significantly longer median OT in Cases was counterbalanced by more favorable EBL and median length of stay and TTC. No statistically significant differences were registered in terms of postoperative complications. Cases showed a 6months longer PFS compared to Controls. However, in multivariate analysis only the administration of Bevacizumab and a shorter TTC were independently associated with a longer PFS. Regarding QoL, no statistically significant differences were registered in Cases between pre- and postoperative GWBS score. Differently from Controls where this difference was statistically significant and a more intense distress were recorded. CONCLUSIONS: Minimally invasive approach could represent an advantageous alternative surgical way to perform interval debulking surgery in this specific subset of patients, with no impact on PFS. Based on these findings a randomized clinical trial is now under evaluation in our Institution.

RESUMO

BACKGROUND: The majority of patients with stage III-IV epithelial ovarian cancer (EOC) relapse after initially responding to platinum-based chemotherapy, and develop resistance. The genomic features involved in drug resistance are unknown. To unravel some of these features, we investigated the mutational profile of genes involved in pathways related to drug sensitivity in a cohort of matched tumors obtained at first surgery (Ft-S) and second surgery (Sd-S). PATIENTS AND METHODS: Matched biopsies (33) taken at Ft-S and Sd-S were selected from the 'Pandora' tumor tissue collection. DNA libraries for 65 genes were generated using the TruSeq Custom Amplicon kit and sequenced on MiSeq (Illumina). Data were analyzed using a high-performance cluster computing platform (Cloud4CARE project) and independently validated. RESULTS: A total of 2270 somatic mutations were identified (89.85% base substitutions 8.19% indels, and 1.92% unknown). Homologous recombination (HR) genes and TP53 were mutated in the majority of Ft-S, while ATM, ATR, TOP2A and TOP2B were mutated in the entire dataset. Only 2% of mutations were conserved between matched Ft-S and Sd-S. Mutations detected at second surgery clustered patients in two groups characterized by different mutational profiles in genes associated with HR, PI3K, miRNA biogenesis and signal transduction. CONCLUSIONS: There was a low level of concordance between Ft-S and Sd-S in terms of mutations in genes involved in key processes of tumor growth and drug resistance. This result suggests the importance of future longitudinal analyses to improve the clinical management of relapsed EOC.

RESUMO

OBJECTIVE: To develop an updated laparoscopy-based model to predict incomplete cytoreduction (RT>0) in advanced epithelial ovarian cancer (AEOC), after the introduction of upper abdominal surgery (UAS). PATIENTS AND METHODS: The presence of omental cake, peritoneal extensive carcinomatosis, diaphragmatic confluent carcinomatosis, bowel infiltration, stomach and/or spleen and/or lesser omentum infiltration, and superficial liver metastases was evaluated by staging laparoscopy (S-LPS) in a consecutive series of 234 women with newly diagnosed AEOC, receiving laparotomic PDS after S-LPS. Parameters showing a specificity≥75%, PPV≥50%, and NPV≥50% received 1 point score, with an additional one point in the presence of an accuracy of ≥60% in predicting incomplete cytoreduction. The overall discriminating performance of the LPS-PI was finally estimated by ROC curve analysis. RESULTS: No-gross residual disease at PDS was achieved in 135 cases (57.5%). Among them, UAS was required in 72 cases (53.3%) for a total of 112 procedures, and around 25% of these patients received bowel resection, excluding recto-sigmoid resection. We observed a very high overall agreement between S-LPS and laparotomic findings, which ranged from 74.7% for omental cake to 94.8% for stomach infiltration. At a LPS-PIV≥10 the chance of achieving complete PDS was 0, and the risk of unnecessary laparotomy was 33.2%. Discriminating performance of LPS-PI was very high (AUC=0.885). CONCLUSIONS: S-LPS is confirmed as an accurate tool in the prediction of complete PDS in women with AEOC. The updated LPS-PI showed improved discriminating performance, with a lower rate of inappropriate laparotomic explorations at the established cut-off value of 10.

RESUMO

OBJECTIVE: To analyze the feasibility of total mesometrial resection by laparoscopy (L-TMMR) in a multicentric series of early stage cervical cancer. METHOD: We prospectively evaluated a consecutive series of cervical cancer patients with pre-operative FIGO stages IA2-IB1 at the Catholic University in Rome and in Campobasso and the Charitè University in Berlin. All cases were assessed at pre-operative MRI scan and clinically confirmed by investigation under anesthesia, adhering strictly to the FIGO criteria. The surgical and post-surgical data were collected. RESULTS: 104 women with cervical cancer were admitted between July 2013 and August 2014 and among them 71 patients with pre-operative FIGO stages IA2-IB1 were treated with L-TMMR. One laparotomic conversion was registered. The median operative time was 260min (120-670min), estimated blood loss was 100cm(3) (25-900cm(3)), and the median length of hospital stay was 6days (2-26days). We observed 8 intra-operative complications including a vascular injury of the left internal iliac vein that caused conversion, 6 vesical injuries and 1 ureteral injury managed laparoscopically. Two vescico-vaginal fistula and one hemoperitoneum were observed as major post-operative complications (4.2%). CONCLUSION: L-TMMR can be safely performed in selected cervical cancer patients. Further larger prospective trials are needed to evaluate the oncological outcome of patients undergoing this surgical procedure.

RESUMO

STUDY QUESTION: What is the risk of complications after uterine leiomyoma embolization and what are the factors associated with complications? SUMMARY ANSWER: The cumulative risk of complications after embolization is relatively low even in the long term, but submucosal leiomyoma location may increase the risk. WHAT IS KNOWN ALREADY: A broad spectrum of complications after leiomyoma embolization have been described with widely varying rates. There is uncertainty over the actual risk of complications and the factors associated with this risk. STUDY DESIGN, SIZE, DURATION: This was a prospective cohort study of 288 consecutive women undergoing leiomyoma embolization in the general gynaecology clinic of a university teaching hospital between January 2001 and December 2010. PARTICIPANTS/MATERIALS, SETTING, METHODS: Complications occurring after embolization were categorized as major or minor according to the severity of their impact on health, the level of care required and the outcome. Cumulative complication rates were estimated by survival analysis and log-rank tests according to baseline variables. Multivariable Cox proportional hazards analysis was performed to adjust for confounders. MAIN RESULTS AND THE ROLE OF CHANCE: There were 48 patients who experienced a complication at a median of 5 months (95% confidence interval, 4.1-11.4) after embolization. Complications were minor in 38 patients and major in 10 patients. The cumulative overall complication rate was 13% (95% CI, 9.0-17.0) at 6 months, 16% (95% CI, 11.0-20.0) at 1 year, 17% (95% CI, 12.0-22.0) at 3 years and 18% (95% CI, 12.9-22.8) at 5 years. The most frequent complication (19/48, 39.6%) was leiomyoma expulsion, which occurred spontaneously in 13 (68.4%) of these cases and required assistance in 6 (31.6%) cases. Eight (2.8%) patients underwent re-intervention, including six hysteroscopic myomectomies, one laparoscopic myomectomy and one hysteroscopic adhesiolysis, as a result of a complication. Submucosal leiomyoma location was the only baseline variable associated with an increased risk for complications [Hazard ratio (HR), 2.28, 95% CI, 1.24-4.18, P = 0.008]. LIMITATIONS, REASONS FOR CAUTION: Our population did not include women of African descent, who have been reported to be at higher risk of post-procedural complications compared with Causcasian women. If such women were involved in the study, higher morbidity rates might have been observed. WIDER IMPLICATIONS OF THE FINDINGS: Women with submucosal leiomyomas at the time of embolization are more likely to have post-procedural complications. This is important new information for counselling patients contemplating this therapeutic approach. STUDY FUNDING/COMPETING INTERESTS: The authors have no competing interests to declare. The study was not supported by any external grant.

RESUMO

OBJECTIVE: To analyze the impact of secondary cytoreductive surgery (SCS) on survival outcome in a retrospective series of isolated platinum-resistant recurrent ovarian cancer. METHODS: We evaluate a consecutive series of 268 ovarian cancer patients with platinum-resistant relapse. Isolated recurrence was defined as the presence of a single nodule, in a single anatomic site, and was observed in 27 cases (10.1%). In all women the presence of isolated relapse was assessed at radiological evaluation, and surgically confirmed in the SCS group. RESULTS: Among the 27 patients with isolated recurrence, 16 (59.3%) received chemotherapy alone, and 11 (40.7%) complete SCS followed by non-platinum based chemotherapy. No significant differences were observed in the distribution of baseline clinico-pathological characteristics, pattern of recurrent disease, duration of PFI, and type of salvage chemotherapy between the two groups. In the SCS group, 6 patients (54.5%) showed isolated peritoneal relapse and 5 women (45.4%) showed isolated lymph nodal recurrence, and were treated with peritonectomy and lymphadenectomy, according with site of relapse. Two post-operative complications (18.2%) occurred: asymptomatic lymphocele and groin wound dehiscence. SCS significantly prolonged median time to first progression (12 months vs 3 months; p-value=0.016), median time to second progression (8 months vs 3 months; p-value=0.037), and post-relapse survival (PRS) (32 months vs 8 months; p-value=0.002). Residual tumor at 1st surgery (X(2)=5.690; p-value=0.017), duration of PFI (X(2)=5.401; p-value=0.020), and complete SCS (X(2)=4.250; p-value=0.039) retains independent prognostic role for PRS in multivariate analysis. CONCLUSIONS: SCS prolongs PRS compared to chemotherapy alone in isolated platinum-resistant recurrent ovarian cancer.

RESUMO

OBJECTIVE: To analyze the feasibility of laparoscopic/robotic secondary cytoreductive surgery and hyperthermic intraperitoneal intra-operative chemotherapy (SCS+HIPEC) in a retrospective series of isolated platinum sensitive recurrent ovarian cancer. METHODS: We retrospectively evaluated a consecutive series of ovarian cancer patients with isolated platinum sensitive relapse. Isolated relapse was defined as the presence of a single nodule, in a single anatomic site. In all cases the presence of isolated relapse was assessed at pre-operative FDG-PET/CT scan, and confirmed with staging laparoscopy performed immediately before SCS+HIPEC. RESULTS: 84 women with platinum sensitive relapse received SCS+HIPEC during a 4-year period. Among them, 10 cases (11.9%) showed isolated relapse and were treated with laparoscopic/robotic SCS+HIPEC. In all cases complete debulking was achieved. In HIPEC treatment, 9 women received cisplatin at 75 mg/m(2), and the remaining patient oxaliplatin 460 mg/m(2). In 7 patients SCS was performed through the laparoscopic route, and in 3 cases with a robotic approach. The median operative time from skin incision to the end of cytoreductive surgery was 122 min (95-140), estimated blood loss was 50 cm(3) (50-100), and the median length of hospital stay was 4 days (3-7). The interval from surgery to adjuvant chemotherapy was 21 days (19-32). No grade 3/4 surgical, metabolic, or hematologic complications occurred. In all cases post-operative FDG-PET/CT scan was negative, and after a median time of 10 months (6-37) from SCS+HIPEC no secondary recurrence was observed. CONCLUSIONS: Minimally invasive SCS+HIPEC can be safely performed in selected ovarian cancer patients with platinum sensitive isolated relapse.

RESUMO

BACKGROUND: Much attention has been recently focused on the role of fertility-sparing surgery in patients with ovarian cancer. However, few data are currently available on the feasibility of conservative approaches in women with disease extending beyond the ovaries. AIM: This review article aims at summarizing the oncologic and obstetric outcome of patients with stage II-III ovarian cancer treated with fertility-sparing surgery. We also describe a successful conservative management of a stage IIC endometrioid ovarian carcinoma. METHODS: A literature search through Medline was carried out to locate published articles using the following keywords for selection: 'Fertility-sparing surgery and ovarian cancer'. From every single case series, we retrieved data on patients with stage II-III disease submitted to conservative surgery. RESULTS: We identified 21 patients with stage II-III disease receiving fertility-sparing surgery. Recurrent disease was observed in 9 women (42.8%), and 5 (23.8%) of them died of disease. In contrast, a successful obstetric outcome has been reported in 3 cases (14.2%). CONCLUSIONS: Radical surgical staging remains the standard of care for all women with stage II-III disease. A fertility-sparing approach may be considered only in the presence of a favorable histology and a very strong fertility desire.

RESUMO

The emergence of new SARS-CoV-2 variants poses challenges to global surveillance efforts, necessitating swift actions in their detection, evaluation, and management. Among the most recent variants, Omicron BA.2.86 and its sub-lineages have gained attention due to their potential immune evasion properties. This study describes the development of a digital PCR assay for the rapid detection of BA.2.86 and its descendant lineages, in wastewater samples. By using this assay, we analyzed wastewater samples collected in Italy from September 2023 to January 2024. Our analysis revealed the presence of BA.2.86 lineages already in October 2023 with a minimal detection rate of 2% which then rapidly increased, becoming dominant by January 2024, accounting for a prevalence of 62%. The findings emphasize the significance of wastewater-based surveillance in tracking emerging variants and underscore the efficacy of targeted digital PCR assays for environmental monitoring.

RESUMO

BACKGROUND: This systematic review (SR) and meta-analysis aims to compare the surgery-related results and oncological outcomes between SH and RH in patients with early-stage cervical cancer. METHOD: We systematically searched databases including PubMed, Embase and Cochrane to collect studies that compared oncological and surgery-related outcomes between SH and RH groups in patients with stage IA2 and IB1 cervical cancer. A random-effect model calculated the weighted average difference of each primary outcome via Review Manager V.5.4. RESULT: Seven studies comprising 6977 patients were included into our study. For oncological outcomes, we found no statistical difference in recurrence rate [OR = 0.88; 95% CI (0.50, 1.57); P = 0.68] and Overall Survival (OS) [OR = 1.23; 95% CI (0.69, 2.19), P = 0.48]. No difference was detected in the prevalence of positive LVSI and lymph nodes metastasis between the two groups. Concerning surgery-related outcomes, the comprehensive effects revealed that the bladder injury [OR = 0.28; 95% CI (0.08, 0.94), P = 0.04] and bladder disfunction [OR = 0.10; 95% CI (0.02, 0.53), P = 0.007] of the RH group were higher compared to the SH group. CONCLUSION: This meta-analysis suggested there are no significant differences in terms of both recurrence rate and overall survival among patients with stage IA2-IB1 cervical cancer undergoing SH or RH, while the SH group has better surgery-related outcomes. These data confirm the need to narrow the indication for RH in early-stage cervical cancer.

RESUMO

PURPOSE: To compare the timing and pattern of recurrence in patients with advanced ovarian cancer (AOC) receiving primary debulking surgery (PDS) versus neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS). METHODS: We retrospectively evaluated a consecutive series of 175 stage IIIC-IV epithelial ovarian cancer patients, with diffuse peritoneal carcinomatosis documented at initial surgical exploration. Forty patients received complete PDS, and the remaining 135 were treated with NACT followed by IDS with absent residual tumor after surgery. RESULTS: No differences were observed in the distribution of clinical pathological characteristics at the time of diagnosis between the two groups. The median follow-up was 31 months (range 9-150 months). We observed 20 (50.0%) recurrences in the PDS group compared to 103 (76.3%) in the IDS group (p = 0.001). Duration of primary platinum-free interval (PFI) was shorter in IDS compared to PDS group (13 vs. 21 months, respectively; p = 0.014). A significantly higher percentage of patients in the IDS group experienced platinum-resistant recurrences (35.9 vs. 5.0%; p = 0.006) and carcinomatosis at the time of relapse (57.3 vs. 20.0%; p = 0.0021). Finally, in women with platinum-sensitive recurrence, we observed a shorter secondary PFI in the IDS compared to PDS group (p = 0.006). CONCLUSIONS: We documented a better behavior of recurrent disease in AOC patients with diffuse peritoneal carcinomatosis treated with complete PDS compared to women submitted to NACT followed by IDS with no residual tumor after surgery.

RESUMO

OBJECTIVE: We evaluated the rates of response, operability and long term survival and toxicities in a large series of locally advanced cervical cancer (LACC) patients administered neoadjuvant chemotherapy (NACT) with paclitaxel, epirubicin and cisplatin (TEP) followed by radical surgery (RS). Patients and methods The study included 75 consecutive stages IB2-IVA patients administered NACT with paclitaxel (175mg/m(2)), epirubicin (100mg/m(2)) and cisplatin (100mg/m(2)) on day 1 of a 3-weekly cycle for 2-4cycles. Patients were evaluated for objective response by RECIST criteria and triaged to RS. Progression-free survival (PFS) and overall survival (OS) were calculated from the date of diagnosis to recurrence/progression of disease or death, respectively. RESULTS: Complete and partial clinical response was observed in 13 and 28 patients (56.1% objective responses); radical surgery was amenable in 52 patients (71.2%): 14 patients showed complete/microscopic response to treatment. Overall, recurrence/progression of disease was observed in 36 patients, and all of them experienced death of disease. In the whole series median PFS was 48months (5-year PFS=51.0%), and median OS was 72months (5-year OS=53.0%). Overall, 195 courses were administered; treatment was delayed in 6.7% of patients, while dose reduction was required in 36.5% of patients. Grade 3 leukopenia affected 22 patients (29.7%), while Grades 3 and 4 neutropenia was documented in 17 (22.9%) and 6 (8.1%) patients. In the whole series, we recorded 1 death whose relation with treatment-induced toxicity could not be ruled out. CONCLUSIONS: TEP provided favorable rates of response and operability in LACC patients, and allowed the obtainment of encouraging survival data without carrying out an excessive toxicity.

RESUMO

OBJECTIVE: We evaluated the clinical outcome and prognostic factors for post-relapse survival (PRS) in a large retrospective series of ovarian cancer patients with localized relapse. PATIENTS AND METHODS: The following radiological inclusion criteria were adopted: relapse in single anatomic site and ≤ 3 nodules. All cases were followed for at least 24 months after recurrent disease. RESULTS: Two hundred twenty ovarian cancer patients met the inclusion criteria. Serous histotype and G3 tumors were observed in 173 (78.6%) and 151 (77.4%) cases, respectively. All women received platinum-based first-line chemotherapy. Overall, the median follow-up was 46 (8-249) months, and platinum-resistant relapse was documented in 51 women (23.2%). Eighty-one patients (36.8%) recurred in the peritoneum (LPeR), 76 patients (34.5%) in the abdominal lymph nodes (LLNR), and 63 patients (28.7%) in parenchymal organs (LPaR); 142 patients (64.5%) recurred with a single nodule; and 78 patients (35.5%) recurred with 2-3 nodules. Secondary cytoreductive surgery (SCS) was attempted in 73 cases (33.2%), and complete debulking was achieved in all patients. On multivariate analysis, platinum-free interval (PFI, χ(2)=13.457, p value=0.001), complete SCS (median PRS, 69 months vs 25 months, p=0.001), anatomic site of relapse (median PRS, 41months in LPeRs, 63 months in LLNRs and 24 months in LPaRs, p=0.001), and number of nodules (median PRS, 58months in patients with one nodule, 24months in patients with 2-3 nodules, p=0.001) were identified as predictors of PRS. CONCLUSIONS: Beside the duration of PFI, the complete SCS, the anatomic site of relapse, and the number of nodules were independent prognostic factor for duration of PRS.

RESUMO

The purpose of the study was to identify the correlation between functional lung parameters to the extent of lung involvement evaluated by High Resolution Computed Tomography (HRCT) in systemic sclerosis (SSc), using a modified score scale. Forty-two patients with established clinical diagnosis of systemic sclerosis were retrospectively selected from the hospital information system and were prospectively included in the study protocol undergoing chest radiography, HRCT and functional lung testing. Lung involvement was assessed by HRCT, lesions were assessed in the individual segments and an additional severity score was introduced by assigning 3 points for bilateral lesions. The total new HRCT score was statistically related to severity of functional lung parameters. Thirty-six out of 42 patients showed an interstitial lung involvement by HRCT: Ground Glass (GG) n=36/42 of which n=27/36 were bilateral; IPM n=30/42, of which 24/30 were bilateral; SL n=33/42 of which 18/33 were bilateral; HC n=6/42 of which 6/6 were bilateral; SC n=6/42 of which 3/6 were bilateral.18/42 had a total score between 0-10, 6/42 between 11-20, 12/42 between 21-30, 6/42 greater than 31. Fifteen out of 42 had restrictive deficit. The results of functional respiratory testing were: FVC less than 80 percent in 12/42 patients (28.5 percent), TLC less than 80 percent in 15/42 patients (35.7 percent), DLCO less than 80 percent in 38/42 patients (90.4 percent) and DLCO/VA less than 80 percent in 21/42 patients (50 percent). The total score was statically related with FVC and TLC and with DLCO and DLCO/VA showing a significant negative correlation found between the total HRCT score of extent of lung damage and lung-function parameter (TLC: r= -0.65, P=0.00000264; FVC: r= -0.50; P=0.000575; DLCO: r= -0.74, P=2.02E-8; DLCO/VA: r= -0.68, P=0.0000005). All Pairwise Multiple Comparison Procedures showed a significant difference between the two rank sums that enclosed the comparison for DLCO/VA vs SCORE and DLCO vs SCORE. In conclusion, our modified score scale gives interesting additional data to evaluate the extension of interstitial lung involvement in SSc. It is inversely proportional to spirometry and DLCO and DLCO/VA. The bilateralism of the lesions is directly proportional to the lung damage.

RESUMO

Mindfulness-based stress reduction, a complementary and alternative therapy, is able to decrease cancer-related fatigue, and stress and to improve the quality of life in cancer patients. Some studies evaluated if mindfulness-based stress reduction could improve some cardiometabolic and cancer risk factors, including systemic chemokines, growth factors, and pro-inflammatory biomarkers (e.g., C-reactive protein, Interleukin-1). In this narrative review, we highlight the pleiotropic beneficial effects of mindfulness-based stress reduction and its clinical impact on cardiovascular and cancer risk factors among patients with cancer in different stages. Moreover, improvements in the overall quality of life, sleep quality, and immune functions [changes in plasma levels of interleukin-4 (IL-4), interferon-γ (INF-γ), and interleukin-10 (IL-10)] will also be discussed. Albeit few clinical studies available in the literature, evidenced the beneficial effects of mindfulness-based stress reduction on the immune and cardiometabolic profile in cancer patients, providing important insights into the closest collaboration between psycho-oncologists, oncologists, and cardiologists.
