Clinical impact of first-line bevacizumab plus chemotherapy in metastatic colorectal cancer of mucinous histology: a multicenter, retrospective analysis on 685 patients

AbstractPurposeIn metastatic colorectal cancer (MCRC), mucinous histology has been associated with poor response rate and prognosis. We investigated whether bevacizumab combined with different chemotherapy regimens may have an impact on clinical outcomes of MCRC patients with mucinous histology.Methods685 MCRC patients were classified in mucinous adenocarcinoma (MC) and non-mucinous adenocarcinoma (NMC) and were treated with first-line bevacizumab plus fluoropyrimidine (FP)-based, oxaliplatin (OXA)-based, irinotecan (IRI)-based, or FOLFOXIRI.ResultsNinety-four (13.7%) patients had MC. With a median follow-up of 50  months, MC patients had a median overall survival (OS) of 28.2 months compared with 27.7 months for the NMC group [hazard ratio (HR) = 0.92; 95% confidence interval (CI) 0.70–1.19,P  =  0.530]. The overall response rates for MC and NMC were 41.5% (95% CI 31.5–51.4) and 62.4% (95% CI 58.4–66.3), respectively (Chi-square test,P

Conclusions: In patients with two cancers, lung cancer is usually the second event, presumably due to comorbidity, survival and our unique population e.g. radical vs adjuvant or palliative intent. The commonest first cancers were breast and prostate. Prostate, bladder and colon cancer developed lung cancer earlier than breast cancer. These data help to inform which cancer types are likely to develop lung cancer and influence tumour surveillance strategies.

ConclusionsExpectedly, adjuvant radiation use was relatively low but was associated with improved OS in patients with both pT4 and positive margins.

ConclusionsThe site of distant metastasis and number of metastasis site were independent prognostic factors for survival of patients with stage IV CAC. This study highlights the need for diverse treatment strategies for patients with different metastatic patterns.

Authors: Dijk FJ, van Dijk M, Dorresteijn B, van Norren K Abstract Dietary supplementation with ω-3 polyunsaturated fatty acids (PUFAs) has been reported to enhance the sensitivity of tumor cells towards chemotherapy. Most enhancing effects are described for ω-3 PUFAs EPA and DHA; less evidence is available with the intermediate DPA. We studied the chemotherapy enhancing effects of EPA, DPA and DHA in murine colon C26 adenocarcinoma cells and showed that DPA displayed similar chemosensitizing effects as EPA. Moreover, EPA supplementation increased cellular DPA content. In a C26 tumor-bearing mouse model...

AbstractPurposeCancer stem cells (CSCs) have been suggested to represent the main cause of tumour progression, metastasis and drug resistance. Therefore, these cells can be an appropriate target to improve cancer treatment.MethodsA novel biodegradable brush copolymeric micelle was synthesized by the ring-opening polymerization (ROP) and reversible addition-fragmentation chain transfer (RAFT) polymerization. The obtained micelle was used for co-delivery of the anticancer drug docetaxel (DTX) and Chrysin (CHS) as an adjuvant on the CSCs originated from Human colon adenocarcinoma cell line. Cancer stem cells were enriched by ...

ConclusionTo optimize targeting and visualization of the surgical field in right pelvic sidewall/paracolic gutter, robotic arms can be placed in a straight line from above the pubic symphysis extending to the left subcostal line and between the midline vertical and midclavicular lines. Robotic tumor debulking should be considered in selected patients with recurrent ovarian cancer who present with oligo-metastatic disease, in the absence of carcinomatosis.

CONCLUSION: Indian patients with colon cancer, at a tertiary referral center, tend to present at more advanced stages of the disease as compared to the West. However, curative treatment with surgery and chemotherapy offers similar survival outcomes when compared stage for stage.

This study used deidentified data from the National Cancer Database. PATIENTS: We queried the national cancer database from 2004 to 2014 for stage 1 to 3 rectal adenocarcinoma treated with only chemotherapy and radiation to definitive doses. Dose escalated therapy was defined as>54 Gy. MAIN OUTCOME MEASURES: Univariable and multivariable analyses were performed to identify sociodemographic, treatment, and tumor characteristics predictive of dose escalation and overall survival. Propensity-adjusted Cox proportional hazard ratios for survival were used to account for indication bias. RESULTS: Among the 6311 patie...
