FTP3.7 Influence of neoadjuvant treatment strategy on operability in locally advanced rectal cancer

چکیده

Abstract Background Neoadjuvant chemoradiotherapy (nCRT) in locally advanced rectal cancer facilitates tumour downstaging and complete pathological response (pCR). systemic chemotherapy (total neoadjuvant chemotherapy, TNT) further improves pCR rates. While some patients forgo surgery, total mesorectal excision (TME) remains the standard of care. TNT appears to be non-inferior nCRT with respect short-term oncological outcomes, little data exists on perioperative outcomes. Factors such as conversion, sphincter preservation anastomosis rates do not impact outcomes but affect quality life (QOL). Methods An institutional colorectal oncology database was interrogated from inception (2009) November 2022. Inclusion criteria comprised histologically confirmed who had undergone therapy TME. Exclusion a non-colorectal primary, those operated emergently or local only. Primary were conversion open, preserving surgery formation. Results In 156 eligible for inclusion (standard nCRT, n= 111, TNT, n=45). Sphincter formation more frequent cohort, while higher cohort. Although these differences statistically different, value approached significance (sphincter preservation, 70% vs 62%, p=0.3484; anastomosis, 72% 64%, p=0.4632, 34% 17%, p=0.0501). Conclusions this series associated lower larger studies will required confirm findings, QOL factors should considered alongside benefits when selecting treatment strategies.

Intensified neoadjuvant radio-chemotherapy for locally advanced rectal cancer: mono-istitutional experience and long-term results

Background: Purpose: The purpose of our study is to demonstrate that intensified neoadjuvant chemo-radiotherapy (CRT) treatment in locally advanced rectal cancer (LARC), aimed at further enhancing the complete pathological response and local disease control, is feasible and well tolerated.  Materials and Methods: From January 2011 to December 2015, 62 patients (women 21, men 41, mean age 61,5, ...

Neoadjuvant concurrent chemoradiotherapy in treating locally advanced rectal cancer.

BACKGROUND Colorectal cancer is a common cancer and a major cause of morbidity and mortality worldwide. Middle to lower rectal cancer, a challenge for surgeons, is problematic. Neoadjuvant concurrent chemoradiotherapy (CCRT), introduced in the last decade, leads the local control of advanced rectal cancer to a high percentage of R0 resection (margin negative under microscopic examination) and a...

A Review of Neoadjuvant Chemoradiotherapy for Locally Advanced Rectal Cancer

Neoadjuvant chemoradiotherapy has become the standard treatment for locally advanced rectal cancer. Neoadjuvant chemoradiotherapy not only can reduce tumor size and recurrence, but also increase the tumor resection rate and anus retention rate with very slight side effect. Comparing with preoperative chemotherapy, preoperative chemoradiotherapy can further reduce the local recurrence rate and d...

Neoadjuvant treatment in rectal cancer: do we always need radiotherapy-or can we risk assess locally advanced rectal cancer better?

There is good quality evidence that preoperative radiotherapy reduces local recurrence but there is little impact on overall survival. This is not completely unexpected as radiotherapy is a localised treatment and local control may not prevent systemic failure. Optimal quality-controlled surgery for patients with operable rectal cancer in the trial setting can be associated with local recurrenc...
