RESUMO

AIMS AND BACKGROUND: The role of chemotherapy in locally advanced or metastatic gastric cancer has been controversial, but chemotherapy has recently been shown to relieve tumor-related symptoms, improve quality of life and prolong survival when compared with best supportive care. Furthermore, palliative chemotherapy is also cost-effective. "Second-generation" combination chemotherapy regimens were developed in the 1980s with high activity in advanced or metastatic gastric cancer (EAP, FAMTX, PELF, ECF). In randomized studies, EAP demonstrated no difference in activity but a significantly higher overall toxicity and toxic death rate than FAMTX, and the ECF (epirubicin, cisplatin, 5-fluorouracil) regimen gave a survival and response advantage, tolerable toxicity, better quality of life and was more cost-effective than FAMTX. METHODS: Sixty patients with locally advanced or metastatic gastric cancer were treated with the ECF regimen (21 weeks of 5-fluorouracil given by continuous infusion through a central line at 200 mg/m2 for 24-hr combined with cisplatin at 60 mg/M2 iv and epirubicin at 50 mg/M2 iv beginning on day 1 and repeated every 3 weeks for 8 courses). There were 42 males and 18 females, with a median age of 64 years (range, 40-74). The median performance status was 1. The histologic type was adenocarcinoma in 44 patients and undifferentiated carcinoma in 16 (27%). Three patients had locally advanced disease (5%) and 57 had metastatic disease (95%). Seven patients (12%) had received prior chemotherapy for advanced disease. RESULTS: All patients were assessable for toxicity and 55 for response (5 had insufficient treatment). Toxicity was mild or moderate, and there was no toxic death. Incidence of WHO toxicity > or = 2 was nausea and vomiting in 3%, mucositis in 3%, leukopenia in 7%, anemia in 3%, and thrombocytopenia in 2%. Port-a-Cath toxicity was thrombosis in 4, dislocation in 2 and infection in 3 patients. Seven complete responses and 13 partial responses (overall response rate, 36%) were achieved, with a response rate of 39% in untreated and 17% in pretreated patients. Nine patients (16%) had stable disease and 26 (47%) progressive disease. Most patients felt symptomatically improved on ECF. CONCLUSIONS: Our study confirms that the ECF regimen has a favorable pattern of toxicity and is feasible on an outpatient basis. However, it did not confirm the high response rate reported in other phase II trials.

RESUMO

About 90% of patients suffering from pancreatic carcinoma are diagnosed with disease that is not amenable to surgical intervention due to local infiltration or the presence of hepatic metastases. Palliative intra-arterial chemotherapy was developed to improve the response in these patients by increasing the antiblastic dose and minimizing the side effects. The aim of this study is to evaluate the efficacy of this treatment comparison to a control group. From December 1994 to February 1997, 135 patients with ductal carcinoma, in whom 68 were stage III and 67 stage IV, with a median age of 63.3 years (range 38.4-79), were enrolled in an open study. Sixty four patients were subjected to a median of 3.5 cycles, according to intra-arterial FLEC protocol. Four patients had a partial response (6.3%), 27 enjoyed a stabilization of their disease (42.2%) and 13 showed disease progression (20.3%). The toxicity was mild. The overall survival was 8.3 months, better in the treated group (9.6 months) in respect to the control one (7.1 months), although this was not statistically significant. The treatment reported here, therefore, does not seem to change the prognosis of patients affected by no resectable pancreatic carcinoma, but it may demonstrate good tolerability and minimal toxicity.

RESUMO

Gastrointestinal autonomic nerve (GAN) tumor is an uncommon specialized form of gastrointestinal stromal tumor (GIST). We report the case of a 46-year-old man affected by this tumor. The neoplasm arose from the sigmoid colon. The patient underwent surgery but eight months later an omental relapse occurred. A second laparotomy was successfully performed and the patient is free of disease at 21 months of follow-up. To our knowledge this is the first case of a large bowel GAN tumor described in the literature.

RESUMO

BACKGROUND: A phase II trial of a new intra-arterial chemotherapy regimen for unresectable pancreatic cancer (UPC). PATIENTS AND METHODS: Ninety-six patients with UPC were treated with intra-arterial chemotherapy at three-weekly intervals. The schedule used was FLEC: 5-fluorouracil 1000 mg/m2, folinic acid 100 mg/m2, carboplatin 300 mg/m2; epirubicin 60 mg/m2. RESULTS: The overall response rates by CT-scan evaluation were: 15% partial response (PR), 44% stable disease (SD), 17% progressive disease (PD). The overall median survival was 9.9 months, and 10.6 and 6.8 for UICC stage III and IV, respectively. Pain reduction occurred in 42% of patients. A weight gain > 7% from baseline occurred in 8% of patients. A total of 341 courses of FLEC were administered. Grade 3-4 hematological toxicity was seen in 25% of patients; ematemesis in 4%; grade 3 gastrointestinal toxicity in 3%; and grade 3 alopecia in 16%. One sudden death, a pre-infarction angina, and a transitory ischemic attack were observed. The only complication related to the angiographic procedure was an intimal dissection of the iliac artery. CONCLUSIONS: The intra-arterial FLEC regimen was well tolerated and active. It requires only one day of hospitalization. Efficacy could only be assessed in a randomized study against a gemcitabine containing regimen.

RESUMO

Mastocytosis is a heterogeneous group of disorders characterized by abnormal growth and accumulation of mast cells in skin, bone marrow, bone, gastrointestinal tract, liver, spleen and lymph nodes. Today, regarding its biological features, mastocytosis (with or without myeloid accompanying disorders) is considered to be a hematologic disease. The classification proposed by Metcalfe in 1991 is the most useful in caring for patients with mastocytosis. In this classification 4 groups are described: 1) indolent mastocytosis with or without extracutaneous involvement; 2) systemic mastocytosis with an associated hematologic disorder; 3) aggressive mastocytosis; 4) mast-cell leukemia. Cutaneous mastocytosis typically presents as urticaria pigmentosa or diffuse cutaneous mastocytosis and these patients usually have a benign course. On the contrary, systemic mastocytosis is a disease with an increased risk to develop an aggressive hematologic disorder. In these patients a second hematologic process, such as myeloproliferative or myelodysplastic syndrome or acute leukemia, may occur. These patients often present without skin involvement and they have a very poor prognosis. Mast cell is a medium-sized granulated cell releasing chemical mediators (histamine, heparin, protease and cytokines). Mast cells originate from pluripotent hemopoietic progenitor cells that express the CD34 antigen. Mast cells are present in the bone marrow and are distributed throughout the connective tissues. Recently a mast-cell growth factor (MGF) has been identified. Clinical symptoms occur from the release of chemical mediators and the pathologic infiltration of cells. Although no effective therapy for patients with Mastocytosis is known, some patients may benefit from corticosteroid and interferon alpha treatment. The present article gives an overview of current knowledge about the biology, heterogeneity and treatment of human mastocytosis.

RESUMO

A case of a 64-year-old man with eccrine carcinoma arising from hand skin is reported. At the time of diagnosis he showed bilateral pneumonic metastases. Although the patient underwent two systemic chemotherapy lines, he showed further progressive disease of the lung. For this reason a third chemotherapy line was started through thoracic stop-flow infusion. In this way, a five month stable disease had been achieved. The patient died 7 months later for progressive disease. The rarity of this disease, the uncertain treatment, the feasibility and efficacy of thoracic stop-flow infusion are underlined and further studies are suggested.

RESUMO

AIMS: To find a means of achieving operability very quickly without the additional discomfort of prolonging systemic chemotherapy. To improve the patient's quality of life by obtaining quick tumor reduction and decreasing systemic toxicity. MATERIALS AND METHODS: From January 1991 to January 1995, 13 patients with locally advanced breast cancer (LABC) and 8 patients with recurrent breast cancer (RBC), were treated by transfemoral Seldinger technique, with the catheter tip placed into the subclavian artery at the basis of the internal mammary artery. The patients received 5-fluorouracil (5FU) 1000 mg, epirubicin (EPI) 30 mg/m2, mitomycin (MMC) 7 mg/m2 over an infusion for 30 minutes. The cycle was repeated every two weeks for three times. RESULTS: The overall response rate was 62%. Stage IIIb and RBC patients had a response rate of 100% and 25% respectively. In respondent patients a measurable response was seen after the first cycle. Ten patients were radically operated. After a media follow-up of 21 months, the overall survival is 52% at 48 months (68% at 48 months and 65% at 34 months for stage IIIb and RBC patients respectively). CONCLUSIONS: PIAC is feasible and effective. In LABC patients it reaches 100% of response rate. Systemic toxicity was absent and the local one was mild. The interval between the starting of PIAC and operation is short. There was an optimal compliance of the patients.

RESUMO

Conventionally, tumor size, axillary lymph nodes status, histologic type and grading, proliferative activity, steroid receptors have been used to predict the natural history of breast cancer. In node-negative patients with breast cancer it is most important to identify biological markers that can predict the risk of systemic relapse. These features have been used to allow selection of the best treatment. In this paper we describe the prognostic significance of new tumoral markers in breast cancer patients without axillary involvement. We analyze the prognostic role and the correlation with response to treatment of these parameters: ploidy, oncogenes, p53, epidermal growth factor receptor and cathepsin D.

RESUMO

Intra-arterial hepatic chemotherapy (LAHC) results in significantly higher response rate than the best systemic treatment of liver metastases from colorectal cancer, but no survival advantage has to date shown because of extra-hepatic progression. From June 1991 to December 1994, twenty patients with hepatic metastases from colorectal cancer were enrolled. All patients underwent laparotomy for the placement of an intra-arterial catheter into the gastroduodenal artery connected with a subcutaneous port. All patients underwent cholecystectomy and biopsy of liver lesion to confirm metastatic disease. Locoregional schedule was: 5-fluorouracil (5FU) 500 mg/sqm, epirubicin (EPI) 13 mg/sqm, mitomycin-C (MMC) 7 mg/sqm, in bolus every 3 weeks. Systemic therapy consisted of leucovorin 500 mg/sqm, over 2 hours and 5FU 600 mg/sqm in bolus every week. Treatment was planned over a six month period. The complete response (CR) plus partial response (PR) rate was 50% of the entire group. The median survival was 18 months and 1- and 2- and 3-year survival rates were 71%, 38% and 20% respectively. Prior to chemotherapy, LDH value and % of liver involvement were the only significant prognostic parameters. Toxicity was absent or mild and no patient stopped treatment because of side effects. Combined systemic and IAHC is an effective treatment for liver metastases from colorectal cancer, with a mild or moderate toxicity. However, more trials are needed, to improve the control of the extrahepatic disease.

RESUMO

Intraarterial chemotherapy is studied as an alternative procedure for the neoadjuvant treatment of locally advanced and recurrent breast cancer. Our study was aimed at investigating the feasibility, the toxicity and the local response rate of an intraarterial chemotherapy regimen including 5-fluorouracil, epirubicin and mitomycin. These drugs were administered angiographically into the subclavian and internal mammary arteries ipsilateral to the lesion. We treated 20 women with a median age of 58 years (range: 42-74 years); 12 patients had locally advanced breast cancer with a median tumor size of 12 cm (range: 6-20 cm) and 8 patients exhibited cutaneous, thoracic or axillary recurrences, with a median lesion size of 6 cm (range: 3-12 cm). In all, we administered 54 cycles of chemotherapy drugs (mean: 2.7 cycles a patient). Most patients were submitted to selective catheterization of the internal mammary artery (44/54 cycles); all the drugs were injected into the subclavian artery only when catheterization of this vessel was unfeasible. No angiography-related toxicity was observed. No systemic, particularly hematological, toxicity was observed. Four patients exhibited skin erythema in the feeding region of the internal mammary artery, 2 hemialopecia, 1 cutaneous steatonecrosis and 1 transient hemiplegia. We obtained 1 complete remission and 11 partial responses, with 60% overall response rate (12/20 patients). All the patients with locally advanced breast cancer had an objective response and the mean interval between the start of therapy and radical mastectomy was only 49 days. In conclusion, intraarterial chemotherapy for locally advanced or recurrent breast cancer is a feasible and well-tolerated tool which needs further studies, particularly to assess its efficacy.

RESUMO

BACKGROUND: The optimal management of primary gastric lymphomas has yet to be defined. In the past surgery was advocated as the optimal first step for patients with PGL. Recently, an increasing number of studies suggest that chemotherapy is as effective as surgery. METHODS: Fourteen patients with PGL were treated with chemotherapy alone. For patients with low-grade lymphoma, chemotherapy consisted of mitoxantrone 5 mg/sqm on days 1 to 3. Treatment courses were administered every 3 weeks up to a maximum of 6 cycles. Patients with high-grade lymphoma received chemotherapy according to the CHOP schedule every 4 weeks up to a maximum of 6 cycles. Two patients with high-grade lymphoma were treated as low-grade lymphoma patients (one because of age and poor performance status, the other because she refused chemotherapy that would cause hair loss). Two patients with low-grade lymphomas who did not respond to mitoxantrone were crossed over to CHOP. RESULTS: All patients were evaluable for toxicity, 13 for response to therapy and survival. Toxicity was mild or moderate. Neither perforation nor hemorrhage was observed. Eleven patients achieved a complete remission (85%), 1 a partial remission (7.5%) and 1 underwent disease progression (7.5%). At a median follow-up of 12 months (range 4-44 months) all complete responders are alive and disease free. CONCLUSIONS: Although the number of evaluable patients is too small to draw any final conclusions, chemotherapy seems to be as effective as surgery in PGL, and stomach preservation improves the quality of life of the patients.

RESUMO

Primary bone non Hodgkin's lymphomas (PBL) are approximately 5% of extranodal lymphomas and 5% of all primary bone tumors. A standard treatment has not been codified yet. The most received only radiotherapy but recently it was introduced combined modality treatment with radiotherapy plus chemotherapy or chemotherapy alone. The authors describe two cases of high grade PBL that received combined treatment with chemotherapy (VACOP-B regimen and monochemotherapy with mitoxantrone respectively) and radiotherapy. The patients achieved complete remission and up to day are alive and disease free at 33 and 15 months from the diagnosis respectively.

RESUMO

Ovarian cancer is most frequently diagnosed at an advanced stage. In recent years there has been intense interest in the chemotherapy of this disease. About cisplatin, the most active agent in the treatment of advanced ovarian cancer, some questions are only partially answered, as the optimal dose, the duration of treatment, the role of ciplatin-based two-, three-, or four-drug regimens, the role of intraperitoneal therapy, the use of old and new drugs in cisplatin-resistant patients. Carboplatin is currently the most important cisplatin analogue with a toxicity pattern very different from that of the parent compound, but, up to date, the combination of these two drugs does not seem to be any better than standard chemotherapy. Among new drugs, three deserve particular attention: taxol, a natural produce from the bark of the Pacific yew Taxus brevifolia, taxotere, a taxoid obtained by semisynthesis from the needles of the European yew Taxus baccata and gemcitabine, a cytostatic agent with a close resemblance to cytosine-arabinoside. Anyway, new approaches must continue to be sought too: among these, probably gene therapy may offer the best mechanism to overcome both intrinsic and acquired drug resistance.

RESUMO

Thirty-three patients with microscopically verified primary or metastatic malignant pleural effusion were studied: 7 had malignant mesothelioma and 26 metastatic pleural disease. The treatment was based on biochemical and clinical studies which show a synergy between cytosine-arabinoside (Ara-C) and cisplatin. These drugs were instilled in the pleural cavity at the dose of 100 mg for Ara-C and 100 mg/m2 for cisplatin. The cavity was drained after 4 h. If it was possible, the treatment was repeated weekly for 3 times and, after a 6-week rest, it could be started again with the same schedule. The overall response rate (complete plus partial remissions) was 74%. Toxicity was mild or moderate. We conclude that the combination of Ara-C and cisplatin is well tolerated and produces a high response rate in the treatment of malignant pleural effusions.

RESUMO

38 patients with advanced breast adenocarcinoma were treated in a phase II study with 5-fluorouracil and high-dose folinic acid combined with cyclophosphamide and mitoxantrone. 6 patients had received prior chemotherapy for advanced disease, all with an anthracycline-containing regimen. Treatment was generally well tolerated. The most common side-effect was myelosuppression, with 1 toxic death due to leukopenia-related sepsis. 1 patient developed severe congestive heart failure 12 months from the end of therapy. 36 patients were evaluable for response. The overall response rate was 55%. Median duration of response was 8 months and median survival time was 16 months. This regimen warrants further investigations.

RESUMO

The authors describe 4 cases of multiple myeloma that developed one or more extraskeletal localizations. They have evaluated the relation between the onset of the extraskeletal localizations and the following myeloma characteristics: tumor burden, clinical phase, chemotherapy response, prognostic significance. All the patients showed these localizations in a plateau phase of myeloma. None of the patients had fever, pancytopenia and in no one the performance status worsened. All patients obtained at least a partial reduction of the localization and only the patient with the retro-orbital localization, got worse and died for myeloma. The other three patients are alive and do not show any sign of progression.
