PURPOSE: Hybrid inverse treatment planning optimization (HIPO) is a new optimization tool for brachytherapy. We verified its utility using treatment plans for combined intracavitary and interstitial brachytherapy in cervical cancer. MATERIALS & METHODS: We compared the manually optimized plan and the plan optimized using HIPO. The plan using HIPO was optimized with three different methods: needle only, tandem and needle, and all applicators. The dose volume histogram (DVH) parameters such as D90 of high risk clinical target volume (HR-CTV) and D2cc of OAR (rectum, sigmoid colon and bladder) were used to evaluate each treatment plan...

Colorectal cancer, a malignant tumor arising from the colon or rectum, is a common cancer in China, with most patients diagnosed at the advanced stage or locally advanced stage. Large tumor size results in the invasion of adjacent organs and the multiple organ involvement, which poses certain challenges for clinical treatment. When facing advanced stage colorectal cancer, some surgeons do not consider surgery, a reasonable option. However, in fact, multi-disciplinary treatment can achieve relatively good treatment outcomes in patients with advanced stage or locally advanced stage colorectal cancer...

A man aged 66 years presented with pneumaturia as a major complaint. Cancer of the sigmoid colon with infiltration to the urinary bladder was diagnosed and the patient underwent colectomy of the sigmoid colon and partial cystectomy of the bladder in May 2015. Histopathologic examinations revealed pT4b, Si(bladder), pN(-), cM0, fStage II . Because intestinal sub-obstruction and lymphatic invasion were present, CapeOX was administered as an adjunctive chemotherapy for the high-risk Stage II cancer. Because Grade 2 peripheral neuropathy appeared as a side effect, the dose was decreased to 80% from the 3 cycle...

A 63-year-old man with bloody stools, anal incompetence, and feeling of fatigue was diagnosed as having a RAS mutanttype rectal cancer with abscess and rectovesical fistula. Computed tomography revealed that the tumor had invaded the seminal vesicle, prostate, and bladder and formed an abscess. In addition, his general condition was poor. Thus, we evaluated the lesion as unresectable. His nutritional status improved, and the infection was controlled after colostomy. Then, we performed chemotherapy with 5-fluorouracil, Leucovorin, and oxaliplatin(FOLFOX)plus bevacizumab...

Non-occlusive mesenteric ischemia(NOMI)causes intestinal necrosis due to irreversible ischemia of the intestinal tract despite the absence of organic obstruction in the mesenteric blood vessels. The disease has extremely poor prognosis. We encountered 2 cases of NOMI hypothesized to have developed after chemotherapy; thus, we report these cases considering the available literature. Case 1: A7 9-year-old man. The patient complained of abdominal pain during the first week after introducing docetaxel for local recurrence of prostate cancer...

PURPOSE: Titanium ring cap applicator (VariSource) was applied in treating cervical cancer patients by using image-guided brachytherapy (IGBT). However, its sizes appeared to be relatively large for most of our patients. Thus, we have developed a specific applicator "Siriraj Ring Cap," which is slightly smaller and more suitable for our patients. This study was to evaluate effectiveness of this equipment. METHODS AND MATERIALS: Locally advanced cervical cancer patients were treated with external beam radiation therapy with or without concomitant chemotherapy...

PURPOSE: To provide a fast computational method, based on the proximal graph solver (POGS) - A convex optimization solver using the alternating direction method of multipliers (ADMM), for calculating an optimal treatment plan in rotating shield brachytherapy (RSBT). RSBT treatment planning has more degrees of freedom than conventional high-dose-rate brachytherapy due to the addition of emission direction, and this necessitates a fast optimization technique to enable clinical usage. METHODS: The multi-helix RSBT (H-RSBT) delivery technique was investigated for five representative cervical cancer patients...

A 73-year-old man with lower abdominal pain was diagnosed at our hospital with sigmoid colon cancer. He had previously undergone radical cystectomy with Indiana pouch construction and gastrectomy to treat bladder cancer and gastric cancer, respectively. We performed a laparoscopic Hartmann's operation with Japanese D3 lymph node dissection. We observed severe adhesion in the abdominal cavity; adhesions between the urostomy and sigmoid colon were particularly severe. The tumor had invaded to the distal rectum, which had adhered to the pubic bone and the previously reconstructed urinary pouch...

BACKGROUND: Plasmacytoid urothelial carcinoma (PUC) is a distinct variant of urinary bladder cancer, with a high propensity for invasion and poor prognosis. These tumors occur most commonly in male patients with the age of reported cases ranging from 46 to 87 years. CASE REPORT: We present a case of a 74-year-old male patient having massive ascites and bilateral lower leg edema. Colonoscopy showed a 3-cm lesion in the sigmoid colon and an edematous nonpapillary tumor was found by cystoscopy in the bladder...

INTRODUCTION: FOLFOX and panitumumab combined chemotherapy plays an important role for metastatic colorectal cancer. However the usefulness of this regimen for neoadjuvant therapy is unclear. CASE REPORT: A 67-year-old man with abdominal pain and pneumaturia was diagnosed with RAS wild-type sigmoid colon cancer with urinary bladder invasion and colovesical fistulas. Because the cancer was considered to be unresectable, a transverse-loop colostomy was performed. Colonoscopy and computed tomography revealed a marked reduction in the size of the primary tumor after six courses of FOLFOX4 (oxaliplatin, leucovorin, and 5-fluorouracil) plus panitumumab...

We analyzed whether TUR was feasible in 4 cases of urinary bladder recurrence of sigmoid colon cancer that invaded into the bladder. Case No. 1 involved a 66-year-old male who presented with sigmoid colon cancer that had invaded the urinary bladder; he underwent sigmoidectomy with partial bladder resection. Six months after the operation, a small, protruded lesion in his urinary bladder was detected and TUR was performed. He has been cancer free for 10 years. Case No. 2 involved a 53- year-old female who underwent sigmoidectomy and hepatectomy for her sigmoid colon cancer and liver metastasis...

OBJECTIVE: To report our experience of radical resection of secondary cancers after ureterosigmoidostomy. Ureterosigmoidostomy was the most common continent urinary diversion before the era of continent cutaneous diversion and neobladders, specifically in children. When performed for bladder exstrophy, patients will live with this kind of diversion for quite a long time. As a result, urologists will be confronted with patients presenting with an adenocarcinoma in their ureterosigmoidostomy...
