Anorectal adenocarcinoma recurrence successfully treated with electrochemotherapy: a case report
We present the case of a patient with tubulovillous adenocarcinoma of the anal canal which relapsed after chemoradiation. The patient refused salvage surgery and was treated with definitive electrochemotherapy under general anesthesia. Tumor electroporation performed with the insertion of three needles in the recurred site was preceded by an intravenous bolus of bleomycin. After the administered treatment, the patient showed a complete clinical response. A year after electrochemotherapy, the patient is free from local disease with excellent preservation of the sphincter function. Electrochemotherapy may be considered as an alternative to surgery in small lesion in the anorectal region when other approaches are excluded.

Conclusion: Our work contributes to the elucidation of the predictive value of DNp73 expression in rectal cancer patients who were given preoperative radiotherapy. Mathematical properties of fuzzy weighted recurrence networks of immunohistochemistry images are not only able to show the predictive factor of DNp73 expression in the patients, but also reveal the identification of non-effective application of radiotherapy to those who had poor overall survival outcome.
AbstractBackgroundEndoscopic tattooing is considered to be a safe procedure to mark a lesion for subsequent surgical resection, and the reported complications are relatively minor. However, here the present case shows tumor traveling through needle tract with tumor inoculation following endoscopic tattooing.Methods and ResultsA 68-year-old female who had a clinical stage I rectal cancer underwent laparoscopic rectal low anterior resection. The pathologic examination of the surgical specimen showed a pathologic stage pT1 invasive adenocarcinoma with a 3-mm focus of tumor cells traveling through a transmural tract and a 0.5-...
ConclusionsPatients with early distal rectal adenocarcinoma who underwent LE had similar survival to patients who underwent APR. LE is an acceptable oncologic treatment strategy for patients with T1 rectal cancers, and LE with CRT is an acceptable oncologic treatment for patients with T2 distal rectal cancers.
Conclusion: This case report helps in understanding the course of progression from rectal cancer to periorbital metastasis.
ConclusionDespite the well documented negative prognostic impact of LPN metastasis, we observed promising outcomes for LPN+ patients treated with an additional radiation boost. Our results suggest that radiotherapy boost to clinically involved, un-resected LPN is an effective treatment approach with limited toxicity. Additional studies are needed to optimize treatment strategy for this unique patient subset.
CONCLUSION: At 17% of its planned accrual, E5204 did not meet its primary endpoint. The addition of bevacizumab to FOLFOX6 in the adjuvant setting did not significantly improve OS in patients with stage II/III rectal cancer. IMPLICATIONS FOR PRACTICE: At 17% of its planned accrual, E5204 was terminated early owing to poor accrual. At a median follow-up of 72 months, there was no significant difference in 5-year overall survival (88.3% vs. 83.7%) or in 5-year disease-free survival (71.2% vs. 76.5%) between the two arms. Despite significant advances in the treatment of rectal cancer, especially in improving local contro...
The optimal timing of surgery in relation to chemoradiation is still controversial. Retrospective analysis has demonstrated in the recent decades that the regression of adenocarcinoma can be slow and not compl...
ConclusionsMIS approaches to rectal cancer resection were associated with improved pathologic and clinical outcomes when compared to the open approach. In this nationwide, facility-based sample of cancer cases in the United States, our data suggest superiority of MIS techniques for rectal cancer treatment.
ConclusionThe random forest classifier based on radiomics features derived from pre-treatment ADC images have the potential to predict tumor resistance to NCRT in patients with LARC, and the use of predicting model may facilitate individualized management of rectal cancer.
