Impaired continence function five years after intensified chemoradiation in patients with locally advanced rectal cancer.

AIMS: While the influence on survival is only seen in patients with complete regression after neoadjuvant treatment in locally advanced rectal cancer the impairment of the continence capacity weighs even more for patients with little oncological benefit. METHODS: Patients treated with intensified preoperative radiochemotherapy patients treated only by TME surgery were asked five years after treatment to complete the Wexner and SF-12 quality of life questionnaire. RESULTS: 25 after neoadjuvant treatment had a median Wexner score of 14 [3-20] after 63 [42-78] months. Histopathological stage or grade of regression did not influence the Wexner score (p = 0.76, resp. p = 0.9). 12% describe themselves as being permanently continent; 40% are stool incontinent "always" or "most of the time". 68% are always wearing pads. 29 patients after TME only showed a median Wexner score of 5 [range 0-17] after 66 months [26-133]. SF-12 showed significantly lower values in physical (p = 0.02) as well as mental summary scales (p = 0.015) in patients after RCTX while patients after radical surgery showed no difference to the norm population. CONCLUSION: This study shows that continence is significantly worse five years after neoadjuvant treatment. Moreover, patients after neoadjuvant treatment and surgery have impaired quality of life compared to norm population. These results may contribute to the discussion of only applying neoadjuvant chemoradiation selectively in patients with advanced rectal cancer.

Local excision of early rectal cancer: is transanal endoscopic microsurgery an alternative to radical surgery?

OBJECTIVE: Transanal endoscopic microsurgery (TEM) allows locally complete excision of rectal neoplasms and provides an alternative to conventional surgery for benign tumours. However, its role in the curative treatment of invasive carcinoma is controversial. This paper examines the results of TEM compared with radical surgery (RS) for T1 rectal cancer. METHODS: 51 patients with T1 rectal tumours treated by RS, or local excision by means of TEM were included. The following parameters were evaluated: operating time, blood loss, hospital stay and complications, as well as local recurrence rate and survival. RESULTS: 17 patients were treated by RS and 34 by TEM. Operative time, blood loss, and duration of hospitalization were significantly lower in the TEM group compared with the RS group. In the RS group there were 4 patients with complications which required an operative revision (23.5%), compared to 1 reintervention (2.9%) in the TEM group. Local recurrence was 5.88% (n = 2) in the TEM group compared with none after RS (p = 0.547). The overall survival and disease-free survival showed not significant statistical differences between both groups (p = 0.59; p = 1.000, resp.). CONCLUSIONS: Although local recurrence was only observed after local excision, patients treated with TEM showed no significant differences in terms of overall survival and disease-free survival compared with patients who underwent RS. Inasmuch as local excision represents a minimally invasive technique in terms of morbidity, mortality and functional outcome, TEM should be offered as a valid option for well selected patients with early rectal cancer.

Local excision of early rectal cancer: is transanal endoscopic microsurgery an alternative to radical surgery?

Objetivo: la cirugía transanal endoscópica (TEM) permite la resección completa de neoplasias de recto siendo una alternativa a la cirugía convencional para tumores benignos. Existe controversia sobre su papel en el tratamiento curativo del cáncer de recto. Esta publicación compara los resultados entre la resección radical (RS) y la exéresis local vía TEM del cáncer de recto en estadio precoz. Métodos: se evaluaron 51 pacientes con neoplasia de recto cuya infiltración se limitaba a la submucosa (T1) y que fueron tratados mediante RS o TEM. Se evaluaron los siguientes parámetros: tiempo quirúrgico, pérdidas sanguíneas, estancia hospitalaria y complicaciones así como recidiva local y supervivencia. Resultados: 17 pacientes fueron tratados mediante RS y 34 vía TEM. El tiempo quirúrgico, el posible sangrado y la estancia hospitalaria fueron significativamente menores en el grupo TEM. En el grupo RS, 4 pacientes presentaron complicaciones que obligaron a una revision quirúrgica (23,5%), comparado con sólo 1 reintervención (2,9%) en grupo TEM. La recidiva local sólo fue observada en dos pacientes (5,88%) del grupo TEM (p = 0,547). La supervivencia global y libre de enfermedad no mostró diferencias estadísticamente significativas entre ambos grupos (p = 0,59 y p = 1,000, respectivamente). Conclusiones: si bien el grupo tratado con TEM advirtió dos recidivas locales, no se observaron diferencias en términos de supervivencia global y libre de enfermedad entre los dos grupos analizados. En tanto la resección local representa una técnica mínimamente invasiva en términos de morbilidad, mortalidad y resultados funcionales, la exéresis mediante TEM debe ser ofertada como una opción válida para pacientes muy bien seleccionados con carcinoma de recto en estadio precoz(AU)

Tumor response to neoadjuvant chemoradiation in rectal cancer: predictor for surgical morbidity?

BACKGROUND: Increasing the rate of pathological complete remissions after neoadjuvant chemoradiation of rectal cancer has become a strategy to further improve the long-term oncological outcome of patients. This report evaluates the influence of preoperative intensified radiochemotherapy on the rate and outcome of surgical complications. MATERIALS AND METHODS: Patients with primary rectal cancer at stages cT3/4cNx or N+ without metastasis were preoperatively treated either with capecitabine and irinotecan or with capecitabine, irinotecan and ceutximab with a concurrent radiation (50.4 Gy). Surgery was scheduled 4-7 weeks after completion of the chemoradiation. Perioperative complications were prospectively documented during the patient's hospital stay. RESULTS: Fifty-nine patients (median age 60; male/female: 46/13) undergoing surgery at a single center were analysed. The median distance of the tumour from the dentate line was 5 cm. The operations performed were low anterior resection (n=45), Hartmann's procedure (n=4) and abdominoperineal resection (n=10). Total mesorectal excision with R0-resection was accomplished in all but one patients. Histopathological regression was described in four grades (0-3) as defined by the Japanese Society for Cancer of the Colon and Rectum. Tumors were called major responsive when assigned to the regression grades 3 or 2, and minor or nonresponsive at regression grades 1 or 0. In total, 33 patients (55.9%) had a regression grade 2 or 3. Among them, 12 patients showed a pathological complete response without any residual cancer cell (20.3%). Seven out of 45 patients (15.5%) with sphincter-preserving surgery suffered from suture breakdown; they all had previously shown a major response of the resected tumor. Two of them died during the hospital stay. CONCLUSIONS: While in general, patients undergoing neoadjuvant intensified treatment suffer from a slight increase in surgical complications, this is markedly enhanced in patients with good treatment responses. Our results underline the oncological benefit of intensified neoadjuvant chemoradiation, but the severity of complications in low rectal anastomosis of patients with good response after neoadjuvant therapy should alert surgeons and oncologists.
