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...

PURPOSE: Rates of contralateral prophylactic mastectomy (CPM) have increased over the last decade; it is important for surgeons and hospital systems to understand the economic drivers of increased costs in these patients. This study aims to identify factors affecting charges in those undergoing CPM and reconstruction. METHODS: Analysis of the Healthcare Cost and Utilization Project National Inpatient Sample was undertaken (2009-2012), identifying women aged ≥18 with unilateral breast cancer undergoing unilateral mastectomy with CPM and immediate breast reconstruction (IBR) (CPM group), in addition to unilateral mastectomy and IBR alone (UM group)...

Robot-assisted radical cystectomy (RARC) has been adopted widely in many centres, owed largely to the success of robot-assisted laparoscopic prostatectomy (RALP). It aims to replicate the oncological outcomes of open radical cystectomy (ORC), while providing a shorter recovery period. Despite this, previous RCTs have failed to show a benefit for RARC over ORC. These trials have compared extracorporeal RARC (eRARC) with ORC, which requires a further incision to mobilise the bowel for urinary reconstruction with an open technique...

OBJECTIVES: Inclusion of 3-dimensional H magnetic resonance spectroscopic imaging (3D-H-MRSI) in routine multiparametric MRI of the prostate requires good quality spectra and easy interpretable metabolite maps of the whole organ obtained without endorectal coil in clinically feasible acquisition times. We evaluated if a semi-LASER pulse sequence with gradient offset independent adiabaticity refocusing pulses (GOIA-sLASER) for volume selection can meet these requirements. MATERIALS AND METHODS: Thirteen patients with suspicion of prostate cancer and 1 patient known to have prostate cancer were examined at 3 T with a multichannel body-receive coil...

Basal cell carcinoma (BCC) is the most common skin cancer but usually has a good prognosis. However, there is a subset of BCC cases with a less favorable prognosis. For patients with locally advanced, recurrent or metastatic BCCs who are not suitable for surgery or radiotherapy, small-molecule drug inhibitors of hedgehog pathway are a new therapeutic opportunity. Here, we present a case of infiltrative BCC with multiple recurrences. Wide excision with reconstructive plastic surgery was performed initially with adjuvant radiotherapy...

The ability to accurately model evolutionary dynamics in cancer would allow for prediction of progression and response to therapy. As a prelude to quantitative understanding of evolutionary dynamics, researchers must gather observations of in vivo tumor evolution. High-throughput genome sequencing now provides the means to profile the mutational content of evolving tumor clones from patient biopsies. Together with the development of models of tumor evolution, reconstructing evolutionary histories of individual tumors generates hypotheses about the dynamics of evolution that produced the observed clones...

As non-crystallizable polymers, microtubules have been the target of cryo-electron microscopy (cryo-EM) studies since the technique was first established. Over the years, image processing strategies have been developed that take care of the unique, pseudo-helical symmetry of the microtubule. With recent progress in data quality and data processing, cryo-EM reconstructions are now reaching resolutions that allow the generation of atomic models of microtubules and the factors that bind them. These include cellular partners that contribute to microtubule cellular functions, or small ligands that interfere with those functions in the treatment of cancer...

Many dental procedures allow for implant placement in partially or totally edentulous patients. Despite the availability of various implant and abutment types on the market, it often becomes quite challenging to achieve the biological and esthetic goals in a patient who has ridge deficiencies. Where problems will arise is from the lack of adequate bone quality and quantity.1,2 Soft tissue form and maintenance is also a consideration to evaluate.3 Primary reconstructive techniques following segmental mandibulectomy is evolving and improves quality of life...

PURPOSE: Differentiating tumor from its surrounding soft tissues is challenging for x-ray computed tomography (CT). Fluorescence molecular tomography (FMT) can directly localize the internal tumors targeted with specific fluorescent probes. A FMT system was developed and integrated onto a CT guided irradiator to improve tumor localization for image guided radiation. METHODS: The FMT system was aligned orthogonal to the cone beam CT onboard our previously developed image guided small animal arc radiation treatment system (iSMAART)...

BACKGROUND: A defect after partial mastectomy, sometimes, is hard to be filled with patient's own breast tissue. Two different types of oxidized regenerated cellulose (ORC) for filling of partial defects in small-sized breasts were compared with respect to clinicopathologic factors and outcomes. METHODS: A total of 45 patients with breast cancer underwent conventional partial mastectomy with insertion of an ORC filling material. The two filling materials used were a hemostasis-purposed ORC and adhesion barrier-purposed ORC...

The Hartmann procedure - primarily - was introduced for the treatment of cancerous diseases of sigmoid colon and rectum. In the last few years it was performed in cases with complicated inflammation of the left colon, colon cancers with bowel obstruction or perforation, or in the case of insufficiency of the anastomoses, or in urgent operations after traumatics bowel injuries, when making the anastomosis is at very high risk. Later on the restoration of the continuity of the GI tract can be done traditionally (by laparotomy) or laparoscopically...
