ABSTRACT Background The relative rarity of synchronous para-aortic lymph node (PALN) metastasis (SPM) and metachronous PALN recurrence (MPR) in colorectal carcinoma (CRC) patients leads to a limited number of studies on patient management, and no treatment guidelines have been established to date. Objective To assess the prognostic, predictive roles, and long-term outcomes of different management strategies for isolated MPR and SPM in CRC patients to establish the best one. Materials and Methods We included 35 CRC patients with isolated MPR and 25 patients with isolated SPM who underwent curative R0 resection. We performed PALN dissection (PALND) in 15 cases in MPR group and in 10 cases in the SPM group; all remaining patients in both groups underwent chemoradiotherapy (CRT) without further surgical intervention. During the study period of about 5 years, we compared the patients who underwent PALND and those who underwent CRT. Results The overall survival and recurrence-free survival rates were significantly longer in patients who underwent PALND (p = 0.049 and 0.036 respectively).

Abstract Background There are many surgical approaches which described extent of resection of the colon for adequate surgicalmanagement of splenic flexure cancer, but up till now there is no established surgical procedure, this is because the presence of double lymphatic drainage of themesenteric vessels. Segmental resection of the colon for the management of splenic flexure cancer was a recently accepted surgical procedure. Objective In the present study, we aimed to compare three surgical management techniques to clarify the best management approach of Egyptian patients with splenic flexure cancer regarding operative, clinical, and oncological outcomes: segmental resection, and extended left or right hemicolectomy,. Materials and Methods In the present study, we included 90 patients with splenic flexure cancer. Cases were divided into 3 groups. Each group included 30 patients in order to compare three surgical techniques: segmental resection, extended left hemicolectomy, and extended right hemicolectomy. Results We have found no statistically significant differences between the three included groups regarding operative findings, postoperative complications, local recurrence, distant recurrence, disease progression, recurrence-free survival rate, progression-free survival rate, and overall survival rate. The operative time was longer, and the number of lymph nodes was higher in the extended right hemicolectomy group (p<0.001). Conclusion We have shown that segmental resection of the splenic flexure is surgically and clinically suitable for the adequate management of operable cases of carcinoma of the splenic flexure.
