Local Recurrence in the Lateral Lymph Node Compartment: Improved Outcomes with Induction Chemotherapy Combined with Multimodality Treatment.

BACKGROUND: Lateral nodal disease is of major importance in the treatment of rectal cancer in the East, but a mostly neglected entity in the West. In this article, the treatment of recurrences in the lateral compartment (latLRs) in a national tertiary referral center is evaluated. METHODS: Of 214 patients with locally recurrent rectal cancer who underwent multimodality treatment in the Catharina Hospital in the last 10 years, a total of 51 patients with latLR were selected (the latLR region was classified as upper, middle, or lower). Thirteen (25 %) of these patients underwent induction chemotherapy (ICT) prior to chemo(re)irradiation. RESULTS: LatLRs occurred mainly after low and N+ primary tumors. Seven (14 %) patients had a complete response (pCR) and 28 (55 %) underwent an R0 resection. Patients with a lower latLR had the highest chance of undergoing an abdominoperineal resection and resection of anterior organs. ICT resulted in a 31 % pCR rate compared with 8 % without ICT (p = 0.039). Patients who received ICT had an 85 % R0 resection rate, while this was 45 % in patients who did not receive ICT (p = 0.013). The 5-year local re-recurrence (LRR) rate was 64.3 %, and overall survival (OS) was 34.2 %; the only factor improving these was an R0 resection. Five-year survival after multivariate analyses was 10.3 % after an R+ resection compared with 66.8 % after an R0 resection (p = 0.011). CONCLUSIONS: LatLRs impose a major surgical challenge and result in high LRR and low OS. More R0 resections can possibly be achieved with ICT, which is the only factor that can improve LRR and OS.

Measuring the health-related quality of life and sexual functioning of patients with rectal cancer: does type of treatment matter?

The literature on the health-related quality of life (HRQOL) after rectal cancer is growing, however, a comparison between patients with nonadvanced disease (NAD), locally advanced rectal cancer (LARC), locally recurrent rectal cancer (LRRC) and a normative population has not been made. Data on the sexual functioning of patient groups is also scarce. We compared (i) the HRQOL of patients with NAD, LARC, or LRRC, with a special focus on sexual functioning and (ii) the HRQOL of the three treatment groups with a normative population. The EORTC QLQ-C30 and QLQ-CR38 were completed by 80 patients with NAD, 292 LARC patients and 67 LRRC patients. The normative population (n = 350) completed the EORTC QLQ-C30 and the Sexual Functioning and Sexual Enjoyment scales of the CR38. LRRC patients reported a lower Physical Function, Social Function, Future Perspective, Sexual Functioning and more Pain compared with LARC and NAD patients. Also, LRRC patients had a worse Body image than NAD patients and a lower Male Sexual Functioning than LARC patients. More than 75% of men and 50% of women were sexually active preoperative, compared with less than 50% and less than 35% postoperative. Male LRRC patients had more problems with erectile or ejaculatory functioning and felt less masculine than NAD or LARC patients. Women did not differ on Lubrication, Dyspareunia and Body Image. About 10% of patients used aids in order to improve erectile functioning (men) or lubrication (women). The treatment groups reported a lower HRQOL and sexual functioning compared with the normative population.
