Learning curve for robotic-assisted total mesorectal excision: a multicentre, prospective study.

AIM: Robotic-assisted surgery (RAS) is becoming increasingly important in colorectal surgery. Recognition of the short, safe learning curve (LC) could potentially improve implementation. We evaluated the extent and safety of the LC in robotic resection for rectal cancer. METHOD: Consecutive rectal cancer resections (January 2018 to February 2021) were prospectively included from three French centres, involving nine surgeons. LC analyses only included surgeons who had performed more than 25 robotic rectal cancer surgeries. The primary endpoint was operating time LC and the secondary endpoint conversion rate LC. Interphase comparisons included demographic and intraoperative data, operating time, conversion rate, pathological specimen features and postoperative morbidity. RESULTS: In 174 patients (69% men; mean age 62.6 years) the mean operating time was 334.5 ± 92.1 min. Operative procedures included low anterior resection (n = 143) and intersphincteric resection (n = 31). For operating time, there were two or three (centre-dependent) LC phases. After 12-21 cases (learning phase), there was a significant decrease in total operating time (all centres) and an increase in the number of harvested lymph nodes (two centres). For conversion rate, there were two or four LC phases. After 9-14 cases (learning phase), the conversion rate decreased significantly in two centres; in one centre, there was a nonsignificant decrease despite the treatment of significantly more obese patients and patients with previous abdominal surgery. There were no significant differences in interphase comparisons. CONCLUSION: The LC for RAS in rectal cancer was achieved after 12-21 cases for the operating time and 9-14 cases for the conversion rate. RAS for rectal cancer was safe during this time, with no interphase differences in postoperative complications and circumferential resection margin.

Prospective Assessment of First-Year Quality of Life After Pelvic Exenteration for Gynecologic Malignancy: A French Multicentric Study.

BACKGROUND: Pelvic exenteration remains one of the most mutilating procedures, with important postoperative morbidity, an altered body image, and long-term physical and psychosocial concerns. This study aimed to assess quality of life (QOL) during the first year after pelvic exenteration for gynecologic malignancy performed with curative intent. METHODS: A French multicentric prospective study was performed by including patients who underwent pelvic exenteration. Quality of life by measurement of functional and symptom scales was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 (version 3.0) and the EORTC QLQ-OV28 questionnaires before surgery, at baseline, and 1, 3, 6, and 12 months after the procedure. RESULTS: The study enrolled 97 patients. Quality of life including physical, personal, fatigue, and anorexia reported in the QLQ-C30 was significantly reduced 1 month postoperatively and improved at least to baseline level 1 year after the procedure. Body image also was significantly reduced 1 month postoperatively. Global health, emotional, dyspnea, and anorexia items were significantly improved 1 year after surgery compared with baseline values. Unlike younger patients, elderly patients did not regain physical and social activities after pelvic exenteration. CONCLUSIONS: Therapeutic decision on performing a pelvic exenteration can have a severe and permanent impact on all aspects of patients' QOL. Deterioration of QOL was most significant during the first 3 months after surgery. Elderly patients were the only group of patients with permanent decreased physical and social function. Preoperative evaluation and postoperative follow-up evaluation should include health-related QOL instruments, counseling by a multidisciplinary team to cover all aspects concerning stoma care, sexual function, and long-term concerns after surgery.

[Locoregional treatments of brain metastases for patients with metastatic cutaneous melanoma: French national guidelines]. / Traitements locorégionaux de métastase(s) cérébrale(s) chez des patients atteints d'un mélanome cutané métastatique : recommandations nationales françaises.

INTRODUCTION: The management of metastatic cutaneous melanoma is changing, marked by innovative therapies. However, their respective use and place in the therapeutic strategy continue to be debated by healthcare professionals. OBJECTIVE: The French national cancer institute has led a national clinical practice guideline project since 2008. It has carried out a review of these modalities of treatment and established recommendations. METHODS: The clinical practice guidelines development process is based on systematic literature review and critical appraisal by experts. The recommendations are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines are reviewed by independent practitioners in cancer care delivery. RESULTS: This article presents the results of bibliographic search, the conclusions of the literature and the recommendations concerning locoregional treatments of brain metastases for patients with metastatic cutaneous melanoma.

Impact of neoadjuvant chemotherapy cycles prior to interval surgery in patients with advanced epithelial ovarian cancer.

OBJECTIVES: Complete surgery with no macroscopic residual disease (RD) at primary (PDS) or interval debulking surgery (IDS) is the main objective of surgery in advanced epithelial ovarian cancer (EOC). The aim of this work was to evaluate the impact on survival of the number of neoadjuvant chemotherapy (NAC) cycles before IDS in EOC patients. METHODS: Data from EOC patients (stages IIIC-IV), operated on between 1995 and 2010 were consecutively recorded. NAC/IDS patients were analyzed according to the number of preoperative cycles (<4=group B1; >4=group B2) and compared with patients receiving PDS (group A). Patients with complete resection were specifically analyzed. RESULTS: 367 patients were analyzed, 220 received PDS and 147 had IDS/NAC. In group B, 37 patients received more than 4 NAC cycles (group B2). Group B2 patients presented more frequently stage IV disease at diagnosis (p<0.01) compared to groups A and B1. The rate of complete cytoreduction was higher in group B (p<0.001). Patients with no RD after IDS and who had received more than 4 NAC cycles had poor survival (p<0.001) despite complete removal of their tumor (relative risk of death after multivariate analysis of 3 (p<0.001)) with an independent impact from disease stage and WHO performance status. CONCLUSIONS: Patients with advanced EOC receiving complete IDS after more than 4cycles of NAC have poor prognosis. Despite worse prognostic factors observed in this group of patients, our study reinforces the concept of early and complete removal of all macroscopic tumors in the therapeutic sequence of EOC.

Day-care for breast cancer: ambulatory surgery and intra-operative radiation. Techniques and preliminary results of the Centre Val-d'Aurelle--Montpellier.

One-day breast carcinoma treatment is defined as association of ambulatory surgery and intra-operative irradiation. Selection and rigorous process of patients is the key to success. The surgical technique is not changed by the radiotherapy. Patient's satisfaction index is very high. Financial loss should not be a hurdle to its implementation.

[Management of patients with metastatic cutaneous melanoma: French national guidelines. French National Cancer Institute]. / Prise en charge thérapeutique des patients atteints d'un mélanome cutané métastatique : recommandations nationales françaises. L'Institut national du cancer.

BACKGROUND: Recent years have seen the emergence of new molecules for the treatment of patients with metastatic cutaneous melanoma, with significant benefits in terms of survival and the opening of new therapeutic perspectives. In addition, many techniques are currently being developed for locoregional treatment of metastatic sites. Management of metastatic melanoma is thus fast-changing and is marked by innovative therapeutic approaches. However, the availability of these new treatments has prompted debate among healthcare professionals concerning their use and their place in therapeutic strategy. AIMS: Since 2008, the French National Cancer Institute (INCa) has been leading a project to define and diffuse national clinical practice guidelines. It has performed a review of these treatment methods, which it aims to circulate, and it is seeking to develop recommendations in order to allow nationwide implementation of innovative approaches while promoting good use thereof. METHODS: The clinical practice guidelines development process is based on systematic literature review and critical appraisal by experts within a multidisciplinary working group, with feedback from specialists in cancer care delivery. The recommendations are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines are reviewed by independent practitioners in cancer care delivery. RESULTS: This article presents the national recommendations for first- and second-line systemic treatment and for locoregional treatment of metastatic sites in patients presenting metastatic cutaneous melanoma.

Total laparoscopic radical hysterectomy for locally advanced cervical carcinoma (stages IIB, IIA and bulky stages IB) after concurrent chemoradiation therapy: surgical morbidity and oncological results.

OBJECTIVES: To evaluate the surgical outcome and the oncologic results of total laparoscopic radical hysterectomy (TLRH) after neoadjuvant chemoradiation therapy (CRT) for locally advanced cervical carcinoma. METHODS: All patients who underwent TLRH after CRT for stages IIB-IIA and bulky IB diseases were reviewed. The control group for this analysis was a cohort of patients treated with abdominal radical hysterectomy (ARH) after CRT for the same stage cancers. RESULTS: We reviewed 102 patients operated on between 2000 and 2008 (46 TLRH and 56 ARH). Mean age at diagnosis was 44 years, and mean B.M.I was 22.1. There was no difference in tumor characteristics between the two groups. Seven patients in the laparoscopic group required conversion to laparotomy (15%). Mean estimated blood loss (200 vs. 400 mL, p<0.01) and the median duration of hospital stay (5 vs. 8 days, p<0.01) were significantly lower in the laparoscopic group. Morbidity rates and urinary complications were reduced in the laparoscopic group (p=0.04). Local recurrence rates, disease-free and overall survival were comparable in the two groups. Best survival was observed for patients with pathological complete response or microscopic residual disease compared to patients with macroscopic residues (p<0.01). CONCLUSIONS: Radical hysterectomy after CRT is known to be difficult with significant morbidity rates and remains controversial in comparison to exclusive CRT. TLRH after preoperative CRT is feasible for patients with locally advanced cervical cancer in 85% of the cases. For these patients, TLRH compared with ARH was associated with favorable surgical outcome with comparable oncological results.

Aggressive surgical strategies in advanced ovarian cancer: a monocentric study of 203 stage IIIC and IV patients.

AIMS: The standard treatment for advanced ovarian cancer consists of cytoreductive surgery associated with a platinum/paclitaxel-based chemotherapy. Nevertheless, there is still the question as to the extent and timing of the surgical debulking. The aim of this study was to evaluate the place of surgery in the therapeutic sequence. PATIENTS AND METHODS: We reviewed data from all consecutive patients with stage IIIC and IV epithelial ovarian cancer, operated on at our institution between 1990 and 2005. Patients were divided into 2 groups, according to the position of surgery in the therapeutic sequence. Patients in group 1 received initial debulking surgery. Group 2 consisted of patients having received their first debulking after initial chemotherapy. RESULTS: Two hundred and three patients were identified and frequently underwent aggressive surgery, in particular, digestive surgery with bowel resections. Perioperative mortality and morbidity rates were low (2% and 14%, respectively) and there was no difference between the groups. Overall survival in group 1 for patients with complete cytoreduction (residual disease (RD)=0), optimal surgery (RD<1cm) or sub-optimal surgery (RD>1cm) was 50%, 30% and 14%, respectively. In group 2, overall survival following complete surgery was 30%, and no long-term survival was observed when surgery was not complete at the time of interval surgery. Survival was worse for patients who had received more than 4 cycles of neoadjuvant chemotherapy. CONCLUSION: This study confirms the importance of surgery in the prognosis of advanced ovarian cancer. Only the patient subgroup that underwent complete initial or interval surgery was associated with a prolonged remission. Optimal surgery with a controlled morbidity can be achieved in many cases, even if bowel resection is needed, at the time of primary debulking. In the interval cytoreductive surgery subgroup, the response to initial chemotherapy and surgery was found to be essential for prognosis.

Blunt traumatic injuries of the gastrointestinal and biliary tract in childhood. Analysis of 16 cases.

BACKGROUND: Little attention has been given to abdominal hollow viscus injuries in pediatric literature. The purpose of this report is to describe their main features, and the current methods of diagnosis and treatment. METHODS: We reviewed our experience with 16 cases of blunt injuries involving the gastrointestinal (GI) and biliary tract in the last seven years. RESULTS: Male to female ratio was 0.68 and mean age 9.4 years. The site of injury was the stomach in 2 cases, duodenum in 5, jejunum or ileum in 7, caecum in 2, left mesocolon in 2, and gallbladder in 1. Diagnosis of the 8 perforations was clinically suspected in 6, and confirmed by radiography in 6 or surgery in 2, with a mean delay of 0.42 days. Diagnosis of the 11 hematomas was clinically suspected in 6, and confirmed by radiography in 9 or surgery in 2, with a mean delay of 12.6 days. Hematomas were managed nonoperatively, and perforations were surgically or laparoscopically closed. Mortality was 1/16 by pancreatic injury, and morbidity was 4/16. CONCLUSION: Incidence of blunt hollow viscus injuries is low in children. Hematomas are easily recognized by modern radiography, and simply managed nonoperatively. Diagnosis of perforations still remains difficult. This results in dangerous delays for lesions which need prompt repair.
