Abstract
Background Lateral pelvic lymph node (LPLN) is approximately 11–14% and always associated with poorer prognosis. This study investigated the efficacy and safety of simultaneous integrated boost intensity-modulated radiation therapy (SIB-IMRT) based on neoadjuvant chemoradiotherapy (NCRT) on locally advanced rectal cancer (LARC) patients with clinically suspected positive LPLNs. Methods We retrospectively screened distal LARC patients with NCRT in our center from May 2016 and June 2019. The diagnostic criteria of positive LPLN were nodes of over 7 mm in short axis and irregular border or mixed-signal intensity. All patients with clinically suspected positive LPLN received 56–60 Gy SIB-IMRT in the LPLN area. Concurrent chemotherapy regimens were capecitabine as monotherapy treatment or in combination with oxaliplatin. The toxicities, local-regional recurrence (LRR), and disease-free survival (DFS) were investigated. Results Fifty-two eligible patients with clinically suspected positive LPLN were screened and analyzed. The median distance from the distal tumor to the anal verge was 4 cm (range, 0–8 cm), while magnetic resonance imaging (MRI) analysis revealed the median short diameter of the pelvic LPLN to be 8 mm (range, 7–20 mm). There were 28 (53.8%) mesorectal fascia (MRF) positive and 22 (42.3%) extramural venous invasion (EMVI) positive patients. A radiotherapy dose of 41.8 Gy was administered to the pelvic area, while the LPLN received a median SIB dose of 60.0 Gy (range, 56–60 Gy) across 22 fractions. Synchronous capecitabine with or without oxaliplatin was administered during radiotherapy. In summary, 15 (28.8%) patients displayed grade 2–3 radiation-related toxicity, 8 (15.4%) patients underwent additional LPLN dissection, and positive nodes (26 nodes in total) were not observed. One patient suffered a LLR in the presacral region. The median follow-up duration was 21.2 months (range, 4.7–45.0 months), while the duration of 1- and 2-year DFS were 89.9% and 74.6%, respectively. Patients did not display LPLN recurrence. Conclusions The safety and efficacy of SIB-IMRT on clinically suspected positive LPLN of LARC patients were deemed acceptable. Patients did not exhibit in-field LPLN recurrence after NCRT combined with single total mesorectal excision (TME).

Abstract
BACKGROUND To evaluate the benefit with the addition of paclitaxel to cisplatin-based concurrent chemoradiotherapy (C-CRT) for the treatment of locally advanced carcinoma of the uterine cervix in terms of local control, disease free survival (DFS) and overall survival (OS). METHODS From 1/7/2011 to 31/5/2012, 81 women (median age of 50 years) with newly diagnosed, histopathologically proven carcinoma cervix with FIGO stages IIA to IIIB were randomized to two arms-cisplatin 40 mg/m(2)/week for 5 weeks was given in single agent cisplatin (control arm), while cisplatin 30 mg/m(2)/week and paclitaxel 50 mg/m(2)/week for 5 weeks were given in cisplatin and paclitaxel (study arm). External beam radiotherapy (EBRT) was delivered to a total dose of 50 Gray (Gy) in 25 fractions (#) followed by intracavitary (I/C) brachytherapy or supplement EBRT at 20 Gy/10# with 2 cycles of respective chemotherapy. This prospective trial was registered with clinicaltrials.gov (NCT01593306). RESULTS Patients (n=81) had a maximum follow up of 36 months with a median follow up of 29 months. At first follow up study arm showed complete response in 84% vs. 75.6% in control arm (P=0.4095). An increase in toxicities was observed in the study arm in comparison to the control arm in terms of haematological grade II (35% vs. 12.2%), gastrointestinal (GI) grade III (20% vs. 7.4%) and GI grade IV (12.5% vs. 2.4%) toxicities. At median follow-up, the study arm demonstrated enhanced outcomes over the control arm in terms of DFS (79.5% vs. 64.3%; P=0.07) and OS (87.2% vs. 78.6%; P=0.27). CONCLUSIONS Despite the expected increase in manageable toxicities, these early results reveal promise with the inclusion of paclitaxel into the standard cisplatin based chemoradiation regime. Larger multi-institutional studies are justified to confirm a potential for the enhancement of response rates and survival.

Abstract
BACKGROUND Despite being chemosensitive, the majority of triple negative breast cancer (TNBC) patients recur. The primary study objectives were to compare disease free survival (DFS), and overall survival (OS) for TNBC after adjuvant chemotherapy, who underwent maintenance metronomic chemotherapy versus no maintenance therapy. METHODS TNBC patients were eligible for enrolment if they had TNM stages II-III and fit with our inclusion criteria. Patients were assigned to either: group 1, 3 cycles FEC-100 then 3 cycles docetaxel, carboplatin, followed by maintenance metronomic chemotherapy for 1 year; and group 2, 3 cycles FEC-100 then 3 cycles docetaxel. RESULTS Between November 2008 and December 2014, 158 patients (78 group 1, and 80 group 2) were enrolled. The mean age was 46 years. The median DFS for groups 1,2 were 28 and 24 months, respectively; P value 0.05. The median OS for groups 1,2 were 37 and 29 months, respectively; P values 0.04. Additionally, during the follow-up period, the overall distant metastasis recurrence rates for groups 1,2 were 26% and 37% respectively. Finally, treatment protocol was tolerated well in both groups with mild toxicity profiles. CONCLUSIONS Extended adjuvant metronomic chemotherapy achieved significant improvement in the survival and was well tolerated.

Abstract
The insulin-like growth factor receptor-1 (IGF1R) plays an important role in cancer progression. Previous studies have been controversial with respect to the associations between IGF1R expression and non small cell lung cancer (NSCLC) prognosis. Thus, we performed a meta-analysis to investigate the prognostic value of IGF1R expression in NSCLC patients and the relationship between the expression of IGF1R and clinical characteristics. Two independent reviewers searched PubMed, Embase, Ovid Medline and CNKI to identify eligible studies. Overall survival (OS), disease free survival (DFS) and clinicopathological characteristics were collected from included studies. Pooled hazard ratios (HRs) or odds ratios (ORs) with 95% confidence interval (95% CI) were calculated to estimate the effect. 17 studies comprising 3,294 patients were included in this meta-analysis. The results showed IGF1R positive expression was associated with an unfavorable DFS in NSCLC patients on univariate analysis (HR = 1.26, 95% CI: 1.09-1.46, P = 0.002) and multivariate analysis (HR = 1.49, 95% CI: 1.01-2.20, p = 0.045), but the relationship between IGF1R expression and OS have no significant difference on univariate analysis (HR = 0.91, 95% CI: 0.82-1.01, P = 0.157) and multivariate analysis (HR = 0.79, 95% CI: 0.45-1.41, P = 0.427). Ever smoking and smaller tumor size (T1 or T2) were associated with IGF1R positive expression: pooled OR 1.45 (1.13-1.85) and pooled OR 0.61 (0.60-0.95). Our results suggested IGF1R positive expression as an unfavorable factor for DFS in NSCLC patients, and IGF1R expression was associated with smoking status and tumor size.
