[Adjuvant adoptive immunotherapy in patients with stage III and resected stage IV melanoma: a pilot study].

Adoptive immunotherapy trials with tumor infiltrating lymphocytes (TIL) and interleukin-2 (IL-2) were carried out in the treatment of advanced melanoma with a 34% of overall responses (OR). However, theoretically it should be of greater benefit as adjuvant therapy, especially in high-risk stages (stage III and resected stage IV). In a pilot study, 22 patients (aged 23-72 years) with stage III-IV melanoma who underwent radical metastasectomy were reinfused with TIL cultivated and expanded in vitro with IL-2 from surgically removed metastases.

[Are small-size depressed-type colorectal neoplasias really the expression of a early stage of colorectal cancer. Apropos of a clinical case].

A route of colorectal cancer development other than the adenoma-carcinoma sequence has recently become an issue due to the discovery of the depressed-type early colorectal cancers. Despite the protruding shapes of depressed-type early colorectal cancers, they probably have biological characteristics which differ from those of the usual polyp lesions. They show more aggressive behavior than the polypoid type and can arise de novo.

[Locoregional chemotherapy of locally advanced breast cancer in a pre-treated patient: case report].

We report of the use of intra-arterial chemotherapy in one case of locally advanced breast cancer, that had been systemically pre-treated. Locoregional chemotherapy was delivered via percutaneous access. The catheter tip was placed into the subclavian artery and into origin of the internal mammary artery; it was removed after every cycle of treatment.

[Combined treatment of inoperable liver metastases from colorectal cancer].

Aims: Liver resection improves survival in selected patients with colorectal liver metastases. However, the majority of patients with colorectal liver metastases have an inoperable oncological disease. The aim is to investigate whether intra-arterial infusion of chemotherapy, improves response to treatment and may convert a selected group of patients with irresectable liver metastases into an operable state.

[Perianal Bowen's disease: a case report and review of the literature].

Perianal Bowen's disease is a uncommon, slow growing, intraepidermal squamous-cell carcinoma (carcinoma in situ) of the anal region and may be a precursor to squamous carcinoma of the anus. It is associated with cervical and vulvar intraepithelial neoplasia and have human papillomavirus as a common cause. Both sexes and all races are affected, with the highest prevalence in patients aged 20 to 45 years.

[Neurogenic tumors of the mediastinum].

Neurogenic neoplasms represent approximately 20% of the space-occupying lesions in the mediastinum. They are primary tumors originating from structures belonging to the peripheral or sympathetic nervous system, they are most commonly diagnosed in subjects in the age range between 10 and 30 years. Benign forms are significantly more frequent than malignant forms, an observation that was confirmed by our own experience; whether these tumors have a predilection for the male or female sex cannot be concluded from the various case series studied to date.

[Reoperations in lung surgery].

A second thoracotomy in patients who have undergone previous chest surgery can be performed soon or immediately after the first operation and is usually aimed at resolving severe or even life-threatening postoperative complications. Late reoperations, on the other hand, are either performed to resolve complications of previous surgery or to remove second primary lung tumors (SPLCs) or metastases. The most exacting reoperation in this context is completion pneumonectomy, which is particularly indicated in the case of failure of the residual lobe to re-expand after primary surgery; it is also used for--rarely occurring--fistulas of the lobar bronchi and for new ipsilateral primary lung tumors.

[Inguinal hernia repair in a teaching course for surgeons. A training program].

The Authors suggest a training programme for surgeons in post graduates courses. With this object in view, the inguinal hernia repair by Lichtenstein has been chosen as the most suitable one. The training course has been divided into theoretic lessons and surgical practice in the operating theatre, carried out in stages as assistant and then as operating surgeon.

[False aneurysm on dacron prosthesis, 20 years after aortofemoral bypass].

A 85-year-old male developed a false, non septic, non anastomotic aneurysm, 20 years after right aorto-femoral Dacron grafting for claudication. On account of the proximity to the femoral anastomosis, and the association with a profunda femoris stenosis, a conventional surgical repair was preferred to an endovascular treatment. The patient underwent a successful aneurysm resection followed by PTFE interposition between the primary graft and the profunda femoris artery, with uneventful recovery.

[Lymphadenectomy in the surgical treatment of bronchogenic carcinoma].

Bronchogenic carcinoma is one of the tumors with the statistically most markedly rising incidence, at least in western countries. For many years both the resectability and the long-term results have remained invariable due to the serious delay with which the disease is usually diagnosed. In addition, the success of treatment appears to be closely correlated with disease stage; in particular lymph node involvement has a major influence on the long-term survival following adequate treatment.

[Angiodysplasia of the large intestine: unusual rectal localization].

The authors report a case of lower gastrointestinal hemorrhage in a 69-year-old male, in which the sequence colonoscopy-angiography identified the source of bleeding as a rare Angiodysplasia (AD) of the rectum. Such vascular abnormalities are one of the most common causes of major lower gastrointestinal tract bleeding in the elderly and usually occurs predominantly in the right side of the colon. The clinical presentation of Angiodysplasia is varied and accurate diagnosis usually requires a combination of diagnostic techniques such as colonoscopy and angiography.

[The surgery of tumors and "limited situations"].

The term "limit" applied to cancer surgery, denotes the ideological moment beyond which one cannot and should not propose any aggressive treatment. Such limits may concern the operability of a patient and may be represented by some general characteristics independent of the patient's current disease status (e.g.

[Major surgery in thoracic injuries].

Chest injuries have a high and steadily increasing incidence in western countries, but only some of the most common problems they create require an emergency thoracotomy or surgical video thoracoscopy. Flail chest, persistent pneumothorax, massive haemothorax, mediastinal emphysema, cardiac tamponade and intrathoracic foreign bodies can be identified as major surgical problems. Some of such patients (i.

[Current indications for sublobar resection in non-small-cell bronchogenic carcinoma].

Over the past 30 years, there has been considerable controversy regarding the role of segmental and wedge resections in the management of stage I (T1-T2N0M0) non-small-cell lung cancer. Recently, a prospective randomized trial (Lung Cancer Study Group, 1995) revealed unfavorable results after limited resection, which, in early stage lung cancer, remains a reasonable option for patients with compromised pulmonary reserve, especially those in whom a previous contralateral resection has been performed. The following report describes the role of limited resection in the management of patients with T1-T2N0 non-small-cell lung cancer and presents a retrospective review of our series of 125 limited resections out of 1356 resections performed for lung cancer.

Distal polytetrafluoroethylene bypasses in patients older than 75 years.

Hypothesis: Polytetrafluoroethylene (PTFE) alone is justified for infrapopliteal arterial grafting in elderly patients with critical ischemia of the lower limbs who lack a suitable, autogenous saphenous vein.

Design: A consecutive sample clinical study with a mean follow-up of 16 months.

Setting: The surgical department of an academic tertiary care center and an affiliated secondary care center.

Transsternal approach to closure of bronchopleural fistulas after pneumonectomy. A fifteen cases report.

A treatment method for main bronchus fistula after pneumonectomy via median sternotomy was described by P. Abruzzini in 1961. This operation is performed in an area not involved with infection.

Metastasis to the breast of a renal carcinoma: a clinical case.

The breast is an unusual site for metastatic disease, and generally the lesion appears same times after the diagnosis of the primary malignancy. Authors report a case of a breast metastasis from a hypernephroma, six years after nefrectomy.

Second primary lung cancer: possible prediction, treatment and prognosis.

The incidence of second primary lung cancer (SPLC) seems to have increased in recent years. In our series that included more than 4000 patients with lung cancer and 1600 operations, we observed 26 cases of SPLC up until June 1999. We considered the standard criteria accepted by most authors for the selection.

Surgical treatment of T3 lung cancer invading the chest wall.

Lung tumors invading the chest wall are classed as belonging to the T3 group and are considered potentially resectable. Their management, however, is controversial, and extrapleural resection, when possible, is preferred to en bloc resection which is regarded as a far more invasive and dangerous operation. Five year survival rates for completely resected cases range in the literature from 25 to 35%, but survival rates are much worse if lymph node metastases are present.

Malignant tumours of the small intestine: a case of jejunal adenocarcinoma.

The Authors analyse the main problems concerning malignant tumours of the small intestine. They report a case of jejunal adenocarcinoma recently observed. They emphasise the importance of surgery, both diagnostic and therapeutic, even in advanced stages, for the treatment of this neoplasm.

Neurinomas of the brachial plexus: case report.

Neurinomas, also referred to as neurilemmomas and schwannomas, are rare benign tumours of the peripheral nerves, a low proportion of which arise from the brachial plexus. Authors report a case of an ancient schwannoma arising from the brachial plexus. The tumour, usually asymptomatic, may cause sensory radicular symptoms, or rarely motor deficits in the involved arm.

Local anaesthesia with eutectic cream of lidocaine and prilocaine for treatment of cicatrizial phimosis in outpatients.

The authors report their experience in ambulatory treatment of cicatrizial phimosis in outpatients, by using local anaesthesia with eutectic cream of lidocaine and prilocaine. This preliminary study shows that preparation seems to be effective and well tolerated. To the aim of getting a good analgesic result the most important aspects are a careful application of the cream all over the concerned area and an occlusive bandage for 60-90 minutes at least.

Results of distal revascularization in elderly patients for critical ischemia of the lower limbs.

Thirty eight patients over 75 years of age were operated upon of 40 distal arterial revascularizations for critical ischaemia of the lower limbs. Arterial reconstruction was proposed to ambulatory, self sufficient patients, with a patent artery of the leg or the foot in continuity with pedal arch, at arteriography. The revascularized artery was the peroneal in 14 cases, the anterior tibial in 11, the posterior tibial in 9, the dorsalis pedis in 5, and the external plantar artery in 1 case.

Seat-belt-related injuries to the supra-aortic arteries.

Five seat-belt-related injuries occurring in four adults are reported. One injury involved the common carotid artery, two the internal carotid and two the subclavian arteries. Three of the four injured persons were asymptomatic and one had delayed-onset symptoms; none suffered stroke.

Results of bypasses to the anterior tibial artery through the interosseous membrane.

The purpose of the present study was to retrospectively evaluate the results of anatomically tunneled grafts to the anterior tibial artery for distal revascularization in terms of patency and limb salvage rates as well as local morbidity, which can lengthen the postoperative hospital stay. Twenty-three patients received 24 bypasses to the anterior tibial artery, with grafts tunneled through the interosseous membrane. The mean age was 67 years; 10 patients were diabetic, 12 were smokers, 9 presented with significant coronary artery disease, and 2 with chronic renal insufficiency.
