RESUMEN
Urothelial cancer is one of the most common malignancies; after relapse or disease progression available therapeutic options are limited. We analyze efficacy and toxicity of local treatment on metastases using stereotactic body radiation therapy (SBRT) in selected patients with oligometastatic disease from urothelial cancer. A significant percentage of treated lesions achieved local control, with a promising overall response rate. OBJECTIVES: to analyze efficacy and toxicity of local treatment on metastases using stereotactic body radiation therapy (SBRT) in selected patients with oligometastatic disease from urothelial cancer. MATERIALS AND METHODS: Data from clinical records of 19 patients treated in our institution since May 2011 to October 2017 with SBRT for oligometastatic/oligoprogressive urothelial carcinoma were retrospectively collected. Clinical outcomes in terms of local control (LC), response rate, symptoms control, progression free and overall survival (PFS and OS), and adverse events were analyzed and reported. RESULTS: Nineteen patients were treated on 25 metastatic lesions; 5 of them received treatment on multiple sites. After an average follow up of 11.5 months, LC was achieved in 17 lesions (68%) and there was no local recurrence in lesions with complete or partial response. OS was 13.8 months. Adverse events were reported only in 3 patients (5 overall events). No late toxicity was reported. CONCLUSIONS: An approach consisting in SBRT for local treatment of oligometastatic or persistent disease can be effective and safe in selected patients. Prospective studies are needed, to find correct selection criteria and optimal dose and fractionation.

Splenic abscess is a rare condition. Haematogenous seeding to the spleen from an infection at a distant site, most often endocarditis, is been the most common predisposing condition but an increase has been observed in immuno-compromised patients too. Fever, leukocytosis and left upper quadrant pain are suggestive, but the signs and symptoms of splenic abscesses are often non-specific. Rare is the onset with diarrhoea as in our case. Ultrasound and computed tomography are reliable diagnostic tools. Splenectomy and antibiotics are the treatments of choice. We describe a case of splenic abscess with gas level and peritonitis from dissemination of Streptococcus anginosus (of Streptococcus millerii group) from duodenal ulcer contaminated. It was diagnosed with CT, ultrasound, and abdomen X-ray with contrast then treated with splenectomy and peritoneal lavage.

The peritoneal papillary serous carcinoma (PPSC) is a rare tumor more frequently revealed in female. The onset mean age is 56 years. It implicate peritoneum, ovary's surface and pelvis. The histology of this disease is similar to papillary serous carcinoma ovary (PSCO). The PPSC histogenesis is probably correlated to coelomatic embryonal epithelium. Clinical characteristics are abdominal swelling, constipation, nausea, emesis, inappetence, feel unwell, lose weight. The cytoreductive surgery and the cisplatinum chemotherapy, and other treatments like immunotherapy and radiotherapy, increase the PSCP patient survival. A case of a 51 years old patient with previous surgery for breast cancer is here described. She show some of the yet described clinical findings. At the surgery we found the typically serous peritoneal localizations. We performed a debulking, and the patient died 14 months after the operation due to the disease progression.

Plastic and oncological breast surgery have to be considered as two aspects of the same treatment. The term "oncoplastic surgery" refers to the use of plastic surgery techniques in breast cancer surgery, in order to avoid and to correct the adverse aesthetic findings. The care of cosmetic sequelae of breast cancer surgery has reached an important therapeutic role for psychological consequences of disease and because of the higher patients expectations of a good aesthetic result. Considering the concept of oncoplastic surgery, since 1999 the authors began to use a periareolar approach in the breast conserving therapy (BCT), associated to axillary dissection performed through the same periareolar incision. This technique is not different from the traditional quadrantectomy in the extension of the glandular resection, while the skin may be preserved in according to the conventional protocols of BCT. Oncological and aesthetic results have proved to be safe and satisfactory.

BACKGROUND: Studies regarding the associations between different types of cancer in the same patient are very few and not always come to the same conclusions. Several hypothesis are suggested and particularly genetic and socioeconomical ones seem to offer an interpretation of this issue. Early detection of a second neoplasm allows to improve prognosis and survival. The knowledge of correlations between tumors help to select a population, with a high risk to develop a second cancer, to be included in a screening program. Nowadays thanks to early detection of breast cancer, ten years survival is more than 75%. Women who had breast cancer now live longer and so could have a higher risk to develop a second cancer. METHODS: From September 1998 to September 1999 in our Department 71 patients operated for breast cancer, underwent screening colonscopy. No patients refused to be included in the study. Mean age was 61 years (range 36-87). Each patient had a clinician interview in order to explain the goals of the study. RESULTS: Results show that among all patients 3 (4.2%) presented a history of colon cancer, 18.3% (13 cases) presented large bowel polyps. In 84.60% patients (11 cases) polyps were found not over 40 cm. This study shows that 93% of patients (66 cases) had a relative with cancer history. CONCLUSIONS: Our results compared with those of other authors seem to show an increased risk for breast cancer patients in developing polyps or colon cancer, so we suggest to insert sigmoidoscopy in standard follow-up of breast cancer patients.

The increasing of HIV infection in young women as well as prolonged survival let us to register an important rising of breast cancers in such type of patients. The Authors report the case of a 48 year old HIV-positive woman, who underwent surgery because of the histological positivity for cancer of the right breast. It was decided to perform a quadrantectomy and reconstruction with implant, because of the absence of immunodepression. The Authors discuss about indications for reconstructive surgery in seropositive women with breast cancer.

Plastic and oncological breast surgery are becoming more and more closer as one surgical treatment. The term "oncoplastic surgery" refers to the use of plastic surgery techniques in breast cancer surgery, in order to avoid and to correct the adverse aesthetic findings.

The reconstruction of the female breast after mastectomy has become a crucial part of primary breast cancer therapy. Setting of an implant is possible only in case of locally abounding soft tissue coverage and when no radiation has before performed. It is necessary a complete integrity of the submuscolar pocket and good blood supply of the skin to avoid failure of the procedure. In Author's experience, started since 1994, an immediate breast reconstruction after mastectomy is performed using gel-silicon implants directly when it was possible or setting first an expander. In six cases the condition of major pectoralis muscle after mastectomy was so foul that an immediate breast reconstruction with prosthesis was not realizable. However, the Authors tried a new technique using polypropylene mesh sutured on the major pectoralis muscle to cover the muscle partially destroyed. Preliminary data from the 6 pts seems to be encouraging.

The basic assumption as rationale of this research was that DNA repair genes (MMR system) are at beginning of the genetic mutational cascade causing the induction of oncogenesis of sporadic colorectal cancers as well as their multiclonal heterogeneity. In a previous study the Authors randomly selected, from a series of 256 patients, 29 patients up to the age of 60 years who underwent surgery for colorectal carcinoma with radical intent. All selected cases were considered as sporadic cancers from a clinical point of view, since none of them fulfilled the Amsterdam criteria for HNPCC and familial adenomatous polyposis was included too. Mismatch repair gene proteins expression and, in particular, gene hMSH2 protein was investigated by immunohistochemistry analysis. In 12 cases (41.4%) hMSH2 exhibited strong expression in the tumoral cells as well as in the surrounding mucosa and at distant mucosa. In 14 cases (48.3%) loss of hMSH2 protein expression was observed in tumoral cells and low immunoreactivity was detected in peritumoral mucosa while strong hMSH2 expression was observed in distant mucosa. In a third small group of patients (10.3%) loss of hMSH2 protein expression was detected in tumoral, adjacent and at distance normal mucosa. After a five years follow up, 100% of twelve patients of first group are still alive vs 64.3% of fourteen patients of second group, while in the third group only one patient survives. These results support the hypothesis of an involvement of hMSH2 gene defect in development of a subset of sporadic colorectal cancer. For the patients with strong expression of hMSH2 in the tumoral cells as well as in the surrounding mucosa and at distant mucosa, this parameter could represent an independent criterion for a good prognostic value.

Axillary seroma is absolutely the most frequent complication of breast cancer surgery. The Authors have accrued 100 consecutive breast cancer patients in a randomized study in order to compare seroma incidence by removing drains on 2nd postoperative day (1st arm) versus 3rd postoperative day (2nd arm); 48 patients were accrued in the first arm and 52 in the second. All patients received a standard axillary dissection. Two suction drains were placed. A compressive medication was applied after surgery. Patients started physiotherapy on the 1st postoperative day. The overall seroma prevalence was 21%. We have 8/48 (16%) seromas in the 1st group and 13/52 (25%) in the 2nd. No significant differences were registered between two arms. Clinical seroma was treated by needle aspiration and medication with a steroid. Conclusions coming out from this study are: 1) early drains removal doesn't increase seroma rate; 2) axillary clearance has to be performed removing en bloc the fatty tissue respecting surgical plains; 3) apply a compressive bandaging; 4) early arm physiotherapy; 5) medication with steroid may reduce the fluid formation.

The time-resolved diffraction signal from a laser-excited solution has three principal components: the solute-only term, the solute-solvent cross term, and the solvent-only term. The last term is very sensitive to the thermodynamic state of the bulk solvent, which may change during a chemical reaction due to energy transfer from light-absorbing solute molecules to the surrounding solvent molecules and the following relaxation to equilibrium with the environment around the scattering volume. The volume expansion coefficient alpha for a liquid is typically approximately 1 x 10(-3) K(-1), which is about 1000 times greater than for a solid. Hence solvent scattering is a very sensitive on-line thermometer. The decomposition of the scattered x-ray signal has so far been aided by molecular dynamics (MD) simulations, a method capable of simulating the solvent response as well as the solute term and solute/solvent cross terms for the data analysis. Here we present an experimental procedure, applicable to most hydrogen containing solvents, that directly measures the solvent response to a transient temperature rise. The overtone modes of OH stretching and CH3 asymmetric stretching in liquid methanol were excited by near-infrared femtosecond laser pulses at 1.5 and 1.7 microm and the ensuing hydrodynamics, induced by the transfer of heat from a subset of excited CH3OH* to the bulk and the subsequent thermal expansion, were probed by 100 ps x-ray pulses from a synchrotron. The time-resolved data allowed us to extract two key differentials: the change in the solvent diffraction from a temperature change at constant density, seen at a very short time delay approximately 100 ps, and a term from a change in density at constant temperature. The latter term becomes relevant at later times approximately 1 mus when the bulk of liquid expands to accommodate its new temperature at ambient pressure. These two terms are the principal building blocks in the hydrodynamic equation of state, and they are needed in a self-consistent reconstruction of the solvent response during a chemical reaction. We compare the experimental solvent terms with those from MD simulations. The use of experimentally determined solvent differentials greatly improved the quality of global fits when applied to the time-resolved data for C2H4I2 dissolved in methanol.
