Diagnosis and treatment of lymph node metastases of a rectal carcinoid tumor using In111-octreotide-scintigraphy and intraoperative gamma probe detection.

Carcinoids represent 1-2% of the rectal cancer. We report the case of a woman with a rectal carcinoid and a hypogastric node metastasis. We propose a less invasive treatment of the metastase using In11-octreotide-scintigraphy and intraoperative gamma-probe detector.

Reassessing the current TNM lymph node staging for renal cell carcinoma.

OBJECTIVE: The most commonly used staging system for renal cell carcinoma (RCC) is the tumor-node-metastasis (TNM) system. In the most recent TNM edition, lymph node (LN) involvement is defined as pN0, pN1, or pN2, depending on the number of metastatic LNs (none, 1, or >1). This study evaluated the prognostic value of this classification and tried to improve its clinical impact by considering an additional parameter, that is, LN density (ratio between number of positive LNs and total number of LNs retrieved). METHODS: All pathologic reports of radical nephrectomies performed for RCC in two urologic centers between November 1983 and December 1999 were reviewed. For each patient, complete clinical and pathologic data, number of LNs removed, location and number of positive LNs, and LN density were recorded. The Kaplan-Meyer method and the log-rank test were used to calculate cause-specific survival rates and to compare survival curves, respectively. RESULTS: A total of 735 patients underwent radical nephrectomy. Lymphadenectomy was performed in 618 cases, and the rate of positive LNs was 14.2%. The 5-yr cause-specific survival rate of pN+ patients was 18%, with no statistically significant difference between pN1 and pN2. The average number of LNs removed was 13 (range, 1-35). The median number of LNs involved was 3 (range, 1-18). LN density ranged between 3.7% and 100% (median, 22.9%). The number of LNs removed had no impact on survival in pN+ patients. The only significant unfavorable prognostic factors were >4 LNs involved (p = 0.02) and LN density >60% (p = 0.01). CONCLUSION: The results show that in RCC the current TNM stratification of positive LNs is not significantly correlated with prognosis. From our data it appears that classification as < or =4 or >4 LNs involved, supported by LN density, better reflects the impact of the disease on survival.

[False penile shortness]. / La falsa brevità del pene.

The rising interest on male genital aesthetics increased the number of patients complaining of short penis. therefore, the andrologist must be able to perform a correct diagnostic assessment and to make the correct therapeutical choice as well, even if there's no standard yet. The aim of this paper is to discuss some diagnostic troubles about penile shortness and, in particular, to explain the basic surgical strategies suitable for the treatment of "hidden penis".

[The current indications for Madden's radical mastectomy in our experience. A critical review of 201 consecutive patients]. / Attuali indicazioni alla mastectomia radicale secondo Madden nella nostra esperienza. Revisione critica in 201 pazienti consecutive.

The clinical pathological data regarding the 201 patients (203 operations running) who underwent radical mastectomy according to Madden in the II Division of General Surgery at Brescia Civil Hospital in the period 1993-1994, have been reexamined in order to check the real need of radical surgery. This further analysis, apart from the patients with neoplasias of considerable dimensions (T2; > 2 cm), has been carried out on 100 tumors smaller dimensions (T1; < 2 cm) and has confirmed the necessity of radical surgery in 87 cases. Of the 13 operations (6.4%) that have been considered "improper" 2 were due to erroneous clinical staging (dubious cutaneous infiltration) and 5 (2.5%) presented a neoplastic diameter of exactly 2 cm which only partially justified radical surgery. In six patients (2.9%) we haven't found clinical pathological elements which contraindicated conservative surgery.

[Impact of a screening program on the surgical treatment of breast carcinoma]. / Impatto di un programma di screening sul trattamento chirurgico del carcinoma della mammella.

Results are presented concerning the first two cycles of a breast cancer screening program carried out by USSL 41 (the local social health center). 38,000 women were examined in a period ranging from 1987 to 1993 and more than 250 early stage tumors were diagnosed. Early detection by screening is confirmed by tumor size and nodal involvement. Overall, this program carried out in Brescia met requirements set by international and national scientific committees. Good results were obtained as far as quality standards are concerned. The importance of screening is evaluated concerning surgical treatment undergone by the patients. The study of surgical treatment clearly shows the gradual progression of conservative surgery deviating from more destructive operations.

[Intestinal anastomosis with biodegradable ring]. / Anastomosi intestinali mediante anello bioframmentabile (BAR).

The authors report their experience using biofragmentable anastomosis ring (BAR) in bowel anastomosis. Starting January 1993 to February 1994, 46 intestinal anastomoses were performed using BAR, and particularly 39 end-to-end colo-colostomies, 2 end-to-side colo-colostomies and 5 end-to-side ileo-colostomies. 35 patients were affected by colonic neoplasm, 5 patients by diverticular colonic complications- and 5 patients by several unusual bowel diseases. Four emergency operations were performed, while 42 patients had an accurate bowel preparation before surgery. In this series of patients one case of preoperative mortality is reported, due to massive pulmonary embolism. Instead several minor complications occurred in other patients, such as paroxysmal atrial fibrillation (one case), basal pleuritis (one case), hyperpyrexia (three cases), temporary subocclusion or delayed canalization (five cases). Only one patient suffered from intestinal occlusion induced by adhesions and a second laparotomy was required. Delayed canalization seems to be caused by the small size of the BAR employed (25 mm) or by inadequate intestinal preparation, that usually occurs in emergency operations. After surgery all patients were followed up and 18 of them were examined by coloscopy six months after surgery. No clinical problem connected with bowel anastomosis was reported and all anastomosis looked quite previous and resilient. No anastomotic stenosis was found. In our experience and from recent reviewed reports, BAR seems to be a rapid, effective and safe device for sutureless bowel anastomosis.

[Role of surgery in the treatment of acute hemorrhagic non-variceal lesions in the upper gastrointestinal tract]. / Ruolo della chirurgia nel trattamento delle lesioni emorragiche acute non varicose del tratto gastro-intestinale superiore.

From January 1993 to December 1994, out of 244 cases of upper gastrointestinal hemorrhage observed 25 patients underwent surgical treatment. Twenty-nine bleeding varices were excluded from this study. Early endoscopy revealed the source of bleeding almost in all cases (84%). All patients received, at the time of admission, medical treatment associated in 7 cases (28%) to endoscopic injection therapy. Emergency surgery indications were massive bleeding persistent bleeding, rebleeding and macroscopic findings of lesions. The aim of this report is to verify the respective roles of medical, endoscopic and surgical therapies in relation to the nature of the bleeding lesion and the entity of the hemorrhage. Results with regard to indication, clinical data, surgical technique were compared with literature data.

[Thyroid carcinoma in hyperthyroid syndromes]. / Il carcinoma tiroideo nelle sindromi ipertiroidee.

The relationship between hyperthyroidism and carcinoma of the thyroid is still uncertain. The incidence of thyroid carcinoma ranges from 0.3 to 16.6%. Between 1984 and 1994 the Authors observed 9 patients affected with thyroid cancer and toxic nodular goiter (4 patients) or Basedow disease (2 patients) or scintigraphic evidence of single hyperfunctioning nodule (3 patients). Six out of the 9 cases were diagnosed as papillary cancer, while three as follicular cancer. A carcinoma was diagnosed before operation in only one case, while in the other 8 patients, the diagnosis was obtained by histological examination of the specimen. Four patients underwent subtotal thyroidectomy, while five patients underwent radical lobectomy. All patients are alive and in good health; the average follow-up was 48 months.

In agree with President and Committee of Andrological Italian Society (S.I.A.), authors have carried on a research to know: 1) main features of Italian Structures interested in male sexual dysfunction 2) actual trend in diagnosis and therapies of male sexual dysfunction, Authors report results and data about this research, particularly regarding new trends in therapia (therapy).

[Penile prosthesis]. / Gli impianti protesici.

In this article the Authors, after describing the history of the penile prosthesis surgery and analyzing the technical progresses made in the last twenty years, offer their personal experience and data from the most recent literature about treatment of erectile dysfunction through the application af penile prosthesis, about the indications for the operation and the choice of the type of prosthesis. They also explain all the possible complications and eventual mechanical failures, which have considerably decreased in the last few years.

[Cystic adenoid carcinoma of the esophagus. Description of a case and review of the literature]. / Il carcinoma adenoido cistico dell'esofago. Descrizione di un caso e revisione della letteratura.

The clinical and histopathologic characteristics of a case of adenoid cystic carcinoma of the esophagus are reported. The authors reviewed the literature on the matter and stressed the more aggressive behaviour of the tumor that differs from the same tumor of the salivary glands and other anatomical sites. Surgical resection is the treatment of choice, however the aggressiveness of the tumor requires, also, a chemo and radiotherapeutic approach.

Fluorouracil, high-dose folinic acid, low-dose alpha-2b interferon and dipyridamole in the treatment of advanced colorectal cancer. A pilot study.

Twenty-six patients with advanced colorectal cancer were treated with a combination based on multimodal biochemical modulation of 5-fluorouracil by means of high dose folinic acid, low-dose alpha-2b interferon and dipyridamole. The overall response rate was 42% (95% confidence intervals = 23%. 61%) with four complete remissions (15%). The median duration of response was 9 months and the median survival for responders was 15 months (all patients = 12 months). Toxic side effects included oral mucositis (grade III-IV = 38%) and a generally mild flu-like syndrome. This regimen seems active and safe enough to be compared with the combination of fluorouracil and high-dose folinic acid.

[Eosinophilic gastritis. Clinico-pathologic considerations on a case and review of the literature]. / Gastrite eosinofila. Considerazioni clinico-patologiche su di un caso e revisione della letteratura.

The clinical, radiographic and histological features of a case of eosinophilic gastritis in a 26 year old-man without personal or familial signs of allergy are reported. The Authors pointed out the importance of radiographic and histological aspects of the case studied. Therefore they represent essential methods for a correct diagnosis and an appropriate management that in this case is only pharmacological. The diagnosis of eosinophilic gastritis is, however, important for the recognition of specific allergens.

Carcinoma of the gastric stump following partial gastrectomy (Billroth II operation) for benign gastroduodenal lesions. Preliminary results.

A series of 110 patients out of 2,200, who had undergone Billroth II partial gastrectomy for benign lesions, between 1945 and 1980, was reviewed in order to perform clinical, biochemical and endoscopical examinations. In this group 9 patients (8.18%) showed gastric stump cancer and in 4 (3.63%) esophageal cancer was detected. The average time interval between previous operation and carcinoma diagnosis was of 28 years and 6 months. Eight patients out of 9 were males aging from 47 to 82, while the only woman was 65 (overall average: 63). The stump cancer presents at the same age and gives the same symptoms as primitive gastric carcinoma, but with worse results and prognosis. After having underlined some pathogenetic problems, the Authors show personal results and confirm the utility of an accurate endoscopical and clinical follow up especially for patients operated on since more than twenty years.

Extended operations for extracolic invasion by colon cancer.

Out of 618 cases of colon cancer treated between 1976 and 1986, 25 had an unusual local invasion. They underwent radical surgery with total resection of one or more adjacent organs. This group is made of 17 female and 8 male patients, with an average age of 58 years. All the patients underwent resection of the colon with radical excision of the locally invaded organs. Only one case of postoperative death is recorded. Postoperative surgical complications were rare. This experience confirms that colic resection extended to adjacent organs invaded by the tumor gives a low risk of relapse and satisfying long term results in relatively young patients with good general conditions and without remote metastases.
