Clinical Trial
T3+ and T4 rectal cancer patients seem to benefit from the addition of oxaliplatin to the neoadjuvant chemoradiation regimen.
To achieve T-downstaging and better resectability in locally advanced rectal cancer, neoadjuvant radiochemotherapy (RCT) has become the current standard of treatment. A variety of schemes have been used. This study investigates which scheme had the best effect on these parameters. ⋯ Downstaging with neoadjuvant treatment results in an increased number of radical resections. In our study, the combination of capecitabine and oxaliplatin appears to be the most effective regimen for locally advanced rectal cancer tumors. However, longer follow-up will be necessary to confirm this conclusion.

Breast magnetic resonance imaging (MRI) is increasingly used for breast cancer treatment planning. The aim of this study was to evaluate rates of mastectomy and breast-conserving surgery (BCS) in patients who undergo preoperative MRI. ⋯ Preoperative MRI was associated with higher rates of mastectomy and detection of occult contralateral breast cancer, but was not associated with lower reexcision rates.

Multiorgan resection for cancer is considered a demanding laparoscopic procedure. We report a laparoscopic radical nephrectomy and distal splenopancreatectomy for a locally advanced kidney tumor. ⋯ Oncologic rules of an "en bloc" resection can be respected also with a laparoscopic approach.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized trial comparing postoperative adjuvant chemotherapy with cisplatin and 5-fluorouracil versus preoperative chemotherapy for localized advanced squamous cell carcinoma of the thoracic esophagus (JCOG9907).
Patients with esophageal carcinoma receiving postoperative chemotherapy showed superior disease-free survival than those receiving surgery alone in a Japan Clinical Oncology Group trial (JCOG9204). The purpose of this study was to evaluate optimal perioperative timing-that is, before or after surgery-for providing chemotherapy in patients with locally advanced esophageal squamous cell carcinoma. ⋯ Preoperative chemotherapy with cisplatin plus 5-fluorouracil can be regarded as standard treatment for patients with stage II/III squamous cell carcinoma.

Comparative Study
Robotic coloanal anastomosis with or without intersphincteric resection for low rectal cancer: starting with the perianal approach followed by robotic procedure.
Coloanal anastomosis (CAA)/intersphincteric resection (ISR) is a promising method of sphincter-preserving surgery for very low rectal cancer. Recently, a robotic system has been attempted in CAA/ISR. By means of a robotic system, an excellent stereoscopic view may be obtained with high illumination, and adequate traction and countertraction can be easily performed in a narrow pelvis using the Endowrist function. During robotic CAA/ISR, although the robotic system is necessary to perform pelvic dissection that comes before the perianal approach, the huge robotic arms located in the low abdominal region could interfere with comfortable perianal dissection for the surgeon. Therefore, the robotic system has to be withdrawn and then set up again above the patient's abdomen, which is time-consuming. Moreover, this process also makes it difficult to maintain the aseptic circumstance of the robotic system. To address this problem, it is necessary to change the sequence of the procedure. ⋯ Robotic CAA/ISR can be performed with good technical efficiency and acceptable morbidity. Further randomized, controlled studies assessing long-term survival, pelvic autonomic nerve function, and bowel function are needed before robotic CAA/ISR becomes widely accepted. Changing the sequence of the procedure, and thus performing the perianal approach before robotic dissection, may be a feasible method to avoid interference of the robotic system in the surgeon's moves using nonrobotic instruments while performing robotic CAA/ISR.
