Clinical implication of surgically treated early-stage cervical cancer with multiple high-risk factors.

ABSTRACT: Presence of high-risk factor in cervical cancer is known to be associated with decreased survival outcomes. However, the significance of multiple high-risk factors in early-stage cervical cancer related to survival outcomes, recurrence patterns, and treatment implications is not well elucidated.A retrospective study was conducted for surgically treated cervical cancer patients (stage IA2-IIB, n=540). Surgical-pathological risk factors were examined and tumors expressing ?1 high-risk factors (nodal metastasis, parametrial involvement, or positive surgical margin) were eligible for analysis (n=177, 32.8%). Survival analysis was performed based on the number of high-risk factors and the type of adjuvant therapy.There were 68 cases (38.4%) expressed multiple high-risk factors (2 high-risk factors: n=58, 32.8%; 3 high-risk factors: n=10, 5.6%). Multiple high-risk factors remained an independent prognosticator for decreased survival outcomes after controlling for age, histology, stage, and treatment type (disease-free survival: hazard ratio [HR], 2.34; p=0.002; overall survival: HR, 2.32; p=0.007). Postoperatively, 101 cases (57.1%) received concurrent chemoradiotherapy (CCRT) and 76 cases (42.9%) received radiotherapy (RT) alone. CCRT was beneficial in single high-risk factor cases: HRs for CCRT over RT alone for cumulative risk of locoregional and distant recurrence, 0.27 (p=0.022) and 0.27 (p=0.005), respectively. However, tumor expressing multiple high-risk factors completely offset the benefit of CCRT over RT alone for the risk of distant recurrence: HR for locoregional and distant recurrence, 0.31 (p=0.071) and 0.99 (p=0.980), respectively.Special consideration for the significance of multiple high-risk factors merits further investigation in the management of surgically treated early-stage cervical cancer.

Project description:ObjectiveUterine serous carcinoma (USC) is a rare highly aggressive disease. In the present study, we aimed to investigate the survival implication of the systematic lymphadenectomy in patients who underwent surgery for apparent early-stage USC.MethodsConsecutive patients with apparent early-stage USC surgically treated at six Italian referral cancer centers were analyzed. A comparison was made between patients who underwent retroperitoneal staging including at least pelvic lymphadenectomy "LND" vs. those who underwent hysterectomy alone "NO-LND". Baseline, surgical and oncological outcomes were analyzed. Kaplan- Meier curves were calculated for disease-free survival (DFS) and disease-specific survival (DSS). Associations were evaluated with Cox proportional hazard regression and summarized using hazard ratio (HR).ResultsOne hundred forty patients were analyzed, 106 LND and 34 NO-LND. NO-LND group (compared to LND group) included older patients (median age, 73 vs.67 years) and with higher comorbidities (median Charlson Comorbidity Index, 6 vs. 5) (p<0.001). No differences in terms of recurrence rate (LND vs. NO-LND, 33.1% vs. 41.4%; p=0.240) were observed. At Cox regression analysis lymphadenectomy did not significantly influence DFS (HR=0.59; 95% confidence interval [CI]=0.32-1.08; p=0.09), and DSS (HR=0.14; 95% CI=0.02-1.21; multivariable analysis p=0.07). Positive node was independently associated with worse DFS (HR=6.22; 95% CI=3.08-12.60; p<0.001) and DSS (HR=5.51; 95% CI=2.31-13.10; p<0.001), while adjuvant chemotherapy was associated with improved DFS (HR=0.38; 95% CI=0.17-0.86; p=0.02) and age was independently associated with worse DSS (HR=1.07; 95% CI=1.02-1.13; p<0.001).ConclusionsAlthough lymphadenectomy did not show survival benefits in patients who underwent surgery for apparent early-stage USC, the presence of lymph node metastasis was the main adverse prognostic factors, supporting the prognostic role of the retroperitoneal staging also in this histological subtype.

Project description:BackgroundSince the concept of oligometastatic (OM) disease was introduced in the oncological scenario of non-small cell lung cancer (NSCLC), these patients progressively became a new category of stage IV NSCLC in whom the multimodality approach, including surgery, may improve prognosis. This systematic review aimed to investigate the clinical prognostic factors in OM-NSCLC surgically treated with radical intent.MethodsThis systematic review is reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Cochrane's Collaboration Tool was used to determine the risk of bias for the included studies' primary outcome. A search strategy using a combination of free-text words, relevant MeSH headings and appropriate restrictions (time limit: from January 1997 to March 2020, language: English) was designed. Potentially qualified papers were subjected to an in-depth full-text examination after preliminary title/abstract screening to identify studies for inclusion in the systematic review. Data extracted included: study characteristics, baseline patient characteristics, primary and secondary outcomes. The Cochrane's Collaboration Tool was used to determine the risk of bias for included studies' primary outcome. The risk of bias due to incomplete outcome data was evaluated at an outcome level. However, at the study stage, the possibility of bias due to sequence generation, allocation concealment, blinding, selective reporting, or funding was assessed. Two independent observers calculated the probability of bias, and differences were resolved through dialogue and consensus.ResultsNine studies were selected. Overall survival (OS) was 51.8 months and varied from 21.1 to 60 months, but results were not statistically significant. Positive prognostic factors for survival were cessation of smoking, age <60, a histologic grade of G1/G2, pN0. The presence of extra-brain OM and multiple metastases negatively affected survival.DiscussionFor otherwise stable patients with a single organ site with synchronous (or metachronous) extrathoracic M1 disease and no intrathoracic lymph node involvement, aggressive treatment should be used in the absence of randomized evidence to help determine the effective management of OM-NSCLC.

Project description:BACKGROUND:Clinical behaviour of atypical meningiomas is not uniform. While, as a group, they exhibit a high recurrence rate, some pursue a more benign course, whereas others progress early. We aim to investigate the imaging and pathological factors that predict risk of early tumour progression and to determine whether early progression is related to outcome. METHODS:Adult patients with WHO grade II meningioma treated in three regional referral centres between 2007 and 2014 were included. MRI and pathology characteristics were assessed. Gross total resection (GTR) was defined as Simpson 1-3. Recurrence was classified into early and late (??24 vs. >?24 months). RESULTS:Among the 220 cases, 37 (16.8%) patients progressed within 24 months of operation. Independent predictors of early progression were subtotal resection (STR) (p?=?0.005), parafalcine/parasagittal location (p?=?0.015), peritumoural oedema (p?=?0.027) and mitotic index (MI)?>?7 (p?=?0.007). Adjuvant radiotherapy was negatively associated with early recurrence (p?=?0.046). Thirty-two per cent of patients with residual tumour and 26% after GTR received adjuvant radiotherapy. There was a significantly lower proportion of favourable outcomes at last follow-up (mRS 0-1) in patients with early recurrence (p?=?0.001). CONCLUSIONS:Atypical meningiomas are a heterogeneous group of tumours with 16.8% patients having recurrence within 24 months of surgery. Residual tumour, parafalcine/parasagittal location, peritumoural oedema and a MI?>?7 were all independently associated with early recurrence. As administration of adjuvant radiotherapy was not protocolised in this cohort, any conclusions about benefits of irradiation of WHO grade II meningiomas should be viewed with caution. Patients with early recurrence had worse neurological outcome. While histological and imaging characteristics provide some prognostic value, further molecular characterisation of atypical meningiomas is warranted to aid clinical decision making.

Project description:BackgroundAdjuvant therapy for patients with cervical cancer (CC) with intermediate-risk factors remains controversial. The objectives of the present study are to assess the prognoses of patients with early-stage CC with pathological intermediate-risk factors and to provide a reference for adjuvant therapy choice.Materials and methodsThis retrospective study included 481 patients with stage IB-IIA CC. Cox proportional hazards regression analysis, machine learning (ML) algorithms, Kaplan-Meier analysis, and the area under the receiver operating characteristic curve (AUC) were used to develop and validate prediction models for disease-free survival (DFS) and overall survival (OS).ResultsA total of 35 (7.3%) patients experienced recurrence, and 20 (4.2%) patients died. Two prediction models were built for DFS and OS using clinical information, including age, lymphovascular space invasion, stromal invasion, tumor size, and adjuvant treatment. Patients were divided into high-risk or low-risk groups according to the risk score cutoff value. The Kaplan-Meier analysis showed significant differences in DFS (p = .001) and OS (p = .011) between the two risk groups. In the traditional Sedlis criteria groups, there were no significant differences in DFS or OS (p > .05). In the ML-based validation, the best AUCs of DFS at 2 and 5 years were 0.69/0.69, and the best AUCs of OS at 2 and 5 years were 0.88/0.63.ConclusionTwo prognostic assessment models were successfully established, and risk grouping stratified the prognostic risk of patients with CC with pathological intermediate-risk factors. Evaluation of long-term survival will be needed to corroborate these findings.Implications for practiceThe Sedlis criteria are intermediate-risk factors used to guide postoperative adjuvant treatment in patients with cervical cancer. However, for patients meeting the Sedlis criteria, the choice of adjuvant therapy remains controversial. This study developed two prognostic models based on pathological intermediate-risk factors. According to the risk score obtained by the prediction model, patients can be further divided into groups with high or low risk of recurrence and death. The prognostic models developed in this study can be used in clinical practice to stratify prognostic risk and provide more individualized adjuvant therapy choices to patients with early-stage cervical cancer.
