A Herpes simplex virus-1 fatal encephalitis following chemo-radiotherapy, steroids and prophylactic cranial irradiation in a small cell lung cancer patient.

Approximately 20-25% of patients with limited small cell lung cancer (SCLC) can be cured with an aggressive approach (chest radiation concomitant with chemotherapy) followed by prophylactic cranial irradiation (PCI) to a total dose of 30-36Gy with 3-2Gy per fraction, five fractions per week. Steroid prophylactic therapy with dexamethasone is usually prescribed during PCI to minimize acute radiation induced brain oedema. This approach may induce an immunosuppressive condition leading to a reactivation of an endogenous latent Herpes simplex virus and severe or fatal acute encephalitis may occur as our report will show. A 55-year-old man affected by locally advanced SCLC was referred to our institution after four cycles of chemotherapy with a good partial remission. Chest radiation started concomitantly with two cycles of chemotherapy followed by PCI 36Gy total dose and dexamethasone 8mg i.m. daily. Fifteen days after PCI completion the patient developed acute neurological symptoms of confusion, cognitive impairment, fever with shaking requiring severe sedation therapy. Twenty-five days later MRI T1 weighted images showed haemorrhagic streaked lines on cortical convolutions of the right cerebral hemisphere and diffuse oedema suggestive of herpetic encephalitis. The DNA consensus test on cerebrospinal fluid (CSF) was positive for Herpes simplex virus 1 infection (HSV-1). A diagnosis of herpetic encephalitis HSV-1 was made. Antiviral therapy with high doses of acyclovir was prescribed but symptoms did not ameliorate leading to a comatose state. The patient died 55 days after the end of PCI. In eligible SCLC patients, PCI is an important part of an aggressive therapeutic approach that improves overall and disease free survival decreasing the risk of relapse in the brain. A primary infection or a reactivation of an endogenous latent HSV in brain parenchyma under steroid therapy concomitant to brain irradiation may compromise these benefits.

FOLFIRI with or without celecoxib in advanced colorectal cancer: a randomized phase II study of the Gruppo Oncologico dell'Italia Meridionale (GOIM).

BACKGROUND: The aim of the study was to verify the efficacy and safety of the addition of celecoxib to FOLFIRI combination therapy in patients affected by advanced colorectal cancer. PATIENTS AND METHODS: Eighty-one chemotherapy-naïve patients entered in this randomized phase II trial of the GOIM (protocol no. 2301). Patients were randomized to receive FOLFIRI regimen (arm A): irinotecan 180 mg/m(2) on day 1 with LV5FU2 regimen (LV at 100 mg/m(2) administered as a 2-h infusion before FU at 400 mg/m(2) as an intravenous bolus injection, and FU at 600 mg/m(2) as a 22-h infusion immediately after 5-FU bolus injection on day 1 and 2); or FOLFIRI plus celecoxib 400 mg twice daily for 14 days (arm B). Both treatments were repeated every 2 weeks. RESULTS: Seventy-seven patients (38 in arm A and 39 in arm B) were evaluable for response. The overall response rate was 41% in arm A (95% CI 27% to 57%) and 35% in arm B (95% CI 20% to 50%). When only assessable patients were analyzed, overall response rate was 45% in arm A (95% CI 29% to 61%) and 36% in arm B (95% CI 21% to 51%). Median time to progression, median duration of response and survival were, respectively, 8 months, 9 months and 16 months in arm A, and 7 months, 9 months and 19 months in arm B. All patients were evaluable for toxicity, which was globally mild in both arms; grade 3-4 toxicity was uncommon, and gastrointestinal disturbances were the most common. CONCLUSIONS: FOLFIRI regimen is effective and well-tolerated as a first-line treatment in patients with advanced colorectal cancer. The addition of celecoxib to FOLFIRI regimen does not improve results.

FOLFIRI regimen in advanced colorectal cancer: the experience of the Gruppo Oncologico dell'Italia Meridionale (GOIM).

PURPOSE: To verify the experience of the GOIM in the treatment of advanced colorectal cancer patients with the FOLFIRI combination therapy. PATIENTS AND METHODS: Patients entered in three consecutive trials of the GOIM (protocols no. 9706, 9901, and 2301) were reported in this analysis. A total of 287 chemotherapy-naive patients were treated with FOLFIRI regimen: Irinotecan 180 mg/m(2) on day 1 with LV5FU2 regimen (LV at 100 mg/m(2) administered as a 2-hour infusion before FU at 400 mg/m(2) as an intravenous bolus injection, and FU at 600 mg/m(2) as a 22-hour infusion immediately after 5FU bolus injection on day 1 and 2); the treatment was repeated every 2 weeks. RESULTS: 287 patients entered in these three trials, and 264 (92%) were evaluable for response. The overall response rate was 34.5% (95% confidence interval [CI]: 29% to 40%). When only assessable patients were analyzed, overall response rate was 37% (95% CI: 31% to 43%). Median time to progression, median duration of response and survival were 7 months, 10.5 months and 14 months, respectively. All but three patients were evaluable for toxicity which was globally mild; grade 3-4 toxicity was uncommon, and gastrointestinal disturbances were the most common. CONCLUSIONS: FOLFIRI regimen is effective and well-tolerated as first-line treatment in patients with advanced colorectal cancer. Further studies needed to evaluate the improvement in results with the addition of new drugs to this combination therapy.

Phase II study of sequential hormonal therapy with anastrozole/exemestane in advanced and metastatic breast cancer.

Hormonal therapy is the preferred systemic treatment for recurrent or metastatic, post-menopausal hormone-receptor-positive breast cancer. Previous studies have shown that there is no cross-resistance between exemestane and reversible aromatase inhibitors. Exposure to hormonal therapy does not hamper later response to chemotherapy. Patients with locally advanced or metastatic, hormonal receptor positive or unknown, breast cancer were treated with oral anastrozole, until disease progression, followed by oral exemestane until new evidence of disease progression. The primary end point of the study was clinical benefit, defined as the sum of complete responses (CR), partial responses (PR) and > 24 weeks stable disease (SD). In all, 100 patients were enrolled in the study. Anastrozole produced eight CR and 19 PR for an overall response rate of 27% (95% CI: 18.6-36.8%). An additional 46 patients had long-term (> 24 weeks) SD for an overall clinical benefit of 73% (95% CI: 63.2-81.4). Median time to progression (TTP) was 11 months (95% CI: 10-12). A total of 50 patients were evaluated for the second-line treatment: exemestane produced one CR and three PR; 25 patients had SD which lasted > or = 6 months in 18 patients. Median TTP was 5 months. Toxicity of treatment was low. Our study confirms that treatment with sequential hormonal agents can extend the period of time during which endocrine therapy can be used, thereby deferring the decision to use chemotherapy.

Randomised, open-label, phase II trial of paclitaxel, gemcitabine and cisplatin versus gemcitabine and cisplatin as first-line chemotherapy in advanced transitional cell carcinoma of the urothelium.

The purpose of the study was to evaluate the antitumor activity and the safety of paclitaxel combined with gemcitabine and cisplatin in patients affected by advanced transitional cell carcinoma of the urothelium (TCC). Eighty-five patients affected by advanced TCC and measurable disease were randomized to receive either paclitaxel at dosage of 70 mg/m2, gemcitabine 1000 mg/m2 and cisplatin 35 mg/m2 on days 1 and 8 every 3 weeks (GCP) or gemcitabine 1000 mg/m2 on days 1, 8, 15 and cisplatin 70 mg/m2 on day 2 every 4 weeks (GC). All enrolled patients were considered evaluable for response and toxicity (intention to treat). The observed response rate was 43% for GCP and 44% for GC combination, respectively. Median time to treatment failure was 32 weeks for GCP and 26 weeks for GC and overall survival 61 vs 49 weeks, respectively (p-value not significant). Grade 3-4 neutropenia was observed in 49% of patients treated with GCP vs 35% of those treated with GC (P=0.05) and grade 3-4 thrombocytopenia was observed in 36% of GCP treated patients as compared to 21% of those treated with GC (P=0.01). Seven patients over 70 years old or with poor PS were removed from the study: 6 patients from GCP group (2 toxic deaths, 2 grade 4 myelotoxicity and 2 grade 3 asthenia) and 1 from GC group was lost to follow-up after the first cycle. The combination of paclitaxel, gemcitabine and cisplatin is effective in the treatment of TCC. However, the addition of paclitaxel to the combination of gemcitabine plus cisplatin seems to increase toxicity, therefore it seems not suitable for poor PS patients and those over 70 years old. Larger and more powered studies are needed to exactly define the role of paclitaxel in this combination.

Treatment of depression in patients with breast cancer: a comparison between paroxetine and amitriptyline.

In the context of chronic physical illness, such as breast cancer, depression is associated with increased morbidity, longer periods of hospitalization, and greater overall disability. Prompt diagnosis and effective treatment is. therefore, essential. Several small studies have established the efficacy of tricyclic antidepressants (TCAs) in this setting, and the selective serotonin reuptake inhibitors (SSRIs) would appear to be an alternative therapeutic option because of their established efficacy and better tolerability profile. This was a multicenter. double-blind, parallel-group study in which 179 women with breast cancer were randomized to treatment with either the SSRI paroxetine (20-40 mg/day), or the TCA, amitriptyline (75-150 mg/day). After 8-weeks treatment, depressive symptomatology had improved markedly and to a similar extent in both groups on the Montgomery Asberg Depression Rating Scale. Clinical global impression (CGI) Global improvement and Patient global evaluation scales indicated that patients were minimally to much improved at study endpoint: a change from moderately/mildly ill to borderline ill on the CGI severity of Illness scale. A steady improvement in quality of life was also observed in both groups. There were no clinically significant differences between the groups. In total, 47 (53.4%) patients in the paroxetine group and 53 (59.6%) patients in the amitriptyline group had adverse experiences, the most common of which were the well-recognized side-effects of the antidepressant medications or chemotherapy. Anticholinergic effects were almost twice as frequent in the amitriptyline group (19.1%) compared with paroxetine (11.4%). This study has demonstrated that paroxetine is a suitable alternative to amitriptyline for the treatment of depression in patients with breast cancer.

5-Fluorouracil plus high dose levofolinic acid and oral hydroxyurea for the treatment of primary hepatocellular carcinomas: results of a phase II multicenter study of the Southern Italy Oncology Group (G.O.I.M.).

A phase II trial of 5FU in modulation with intravenous high-dose levofolinic acid and oral hydroxyurea (HU) in advanced unresectable hepatocellular carcinoma (HCC). A total of 50 consecutive patients, 38 males (76%) and 12 females (24%), with a mean age of 62 years (range 30-74) and a mean performance status of 80 (KI, range 60-90) were enrolled. The vast majority of patients were therapy-naive, although two patients (4%) had previous surgery and showed progressive disease at entry. No patient had been previously treated with chemotherapy. Five patients had previous hormonotherapy with tamoxifen. Most patients had disease limited to the liver while 12 patients (24%) had also metastatic deposits outside the liver. The treatment plan included: levofolinic acid 100 mg/m2 diluted in 500 cc of normal saline over 2 hour infusion followed by 5FU 600 mg/m2 i.v. bolus. HU 1,000 mg/m2 was given by mouth in three refracted doses starting 6 hours after 5FU. A PR was recorded in only 5 patients (10%; 95% CL 1%-34%) with a median duration of 5.7+ months (range 4.0/6.2 months), a stabilization in 15 (30%) with a median duration of 3.8 months, while 30 patients progressed (60%). PR were seen at liver primary tumor in 4 cases and at soft tissue in 1 case. The median survival was 5.8 months (range 2.0/12.0+). The most frequent toxicities were leukopenia (32%), which however was mild (grade 1-2) in all cases, and grade 1-2 thrombocytopenia observed in 15% of cases. Mild grade 1-2 vomiting was recorded in one third of patients, and grade 1-2 stomatitis in 15%. The combination of 5FU with levofolinic acid and oral HU on a weekly schedule is largely inactive against unresectable or metastatic HCC and results are no better than historical data reported for 5FU alone.

Dose intensification of mitoxantrone in combination with levofolinic acid, fluorouracil, cyclophosphamide and granulocyte colony stimulating factor support in advanced untreated breast cancer patients. A multicentric phase II study of the Southern Italy Oncology Group.

Fifty-five consecutive patients with metastatic breast cancer (MBC) (n = 57) were treated with a combination of levofolinic acid (I-FA) 100 mg/m2 plus 5-fluorouracil (5-FU) 340 mg/m2 i.v. on day 1-3, cyclophosphamide (CTX) 600 mg/m2 i.v. on day 1 and mitoxantrone (DHAD) 12 mg/m2 i.v. on day 1. DHAD dose was progressively escalated by 2 mg/m2/cycle up to 18 mg/m2 in the absence of dose-limiting toxicities. Granulocyte colony stimulating factor (G-CSF) was given s.c. in order to prevent neutropenia. DHAD dosage could be increased to 18 mg/m2 in 66 out of 317 cycles of chemotherapy (21%). In most patients the dose-limiting toxicity was represented by myelosuppression. A statistically significant correlation was found between median white blood cell (WBC) or absolute neutrophil count (ANC) nadir and DHAD dose level. Moreover, a statistically significant correlation was observed between the number of chemotherapeutic cycles, nadir ANC and WBC, and the occurrence of anemia and thrombocytopenia of increasing severity. These data suggest the occurrence of progressive cumulative bone marrow toxicity. Although patients who reached different DHAD levels showed differences in mean dose intensity, such differences were not statistically significant. No correlation was found between the increase in dose intensity and type, rate or duration of objective responses. In patients with metastatic breast cancer the overall response rate was 72% (95% CL 57-84%) with a 18% complete response rate. Median duration of response was 12 and 11 months, respectively, for complete and partial responses. Projected median survival of the whole series of patients with MBC was 18 months. These data demonstrate that the combination of 5-FU with I-FA, CTX and DHAD is very active against MBC. G-CSF use allows the increase DHAD dosage up to 18 mg/m2/cycle, but its use may be linked to the occurrence of sometimes severe cumulative hematological toxicity.

Treatment of advanced adenocarcinomas of the exocrine pancreas and the gallbladder with 5-fluorouracil, high dose levofolinic acid and oral hydroxyurea on a weekly schedule. Results of a multicenter study of the Southern Italy Oncology Group (G.O.I.M.).

BACKGROUND: To date there is no established chemotherapeutic treatment for patients with unresectable locally advanced and/or metastatic carcinomas of the exocrine pancreas or the gallbladder. A multicenter Phase II trial has been performed by the Southern Italy Oncology Group with the aim of evaluating the clinical effectiveness and tolerability of weekly 5-fluorouracil (5-FU) in modulation with intravenous (i.v.) high dose levofolinic acid and oral hydroxyurea. METHODS: A total of 70 patients fulfilling the standard eligibility for a Phase II study were enrolled in the trial. Forty patients had advanced pancreatic adenocarcinoma and 30 had advanced gallbladder carcinoma. The treatment schedule was: levofolinic acid, 100 mg/m2, in 500 mL of normal saline over 2-hour infusion followed by 5-FU, 600 mg/m2 i.v. bolus, and oral hydroxyurea, 1000 mg/m2, for 1 day every week for 6 consecutive weeks followed by 15 days of rest. RESULTS: Among the 40 patients with pancreatic adenocarcinoma, 5 (12.5%; 95% confidence level [CL], 8.5-16.5%) showed a partial response with a median duration of 5.6+ months, and 13 had stable disease. Twenty-two patients progressed. Median survival was 5.8 months. Among patients with advanced gallbladder carcinoma, 9 of 30 had a partial response (30%; 95% CL, 26-34%) with a median duration of 6.5 months, and 8 (27%) had stabilization of disease. Thirteen patients showed progressive disease. Median overall survival was 8 months. Toxicity was mild, with Grade 1 to 2 leukopenia and gastrointestinal toxicity the most frequent side effects. No chemotherapy-related deaths were observed. CONCLUSIONS: 5-FU in modulation with i.v. levofolinic acid and oral hydroxyurea on a weekly schedule is well tolerated by the vast majority of patients with locally advanced and/or metastatic carcinoma of the pancreas or the gallbladder. Although response rate and overall survival for patients with pancreatic adenocarcinoma are far from acceptable, the 30% overall response rate achieved in patients with advanced gallbladder carcinoma suggests that 5-FU in modulation with levofolinic acid and hydroxyurea is active in this neoplasm. The combination of modulated 5-FU with other antineoplastic drugs seems worthy of clinical testing in further controlled trials.

Efficacy of the association of folinic acid and 5-fluorouracil alone versus folinic acid and 5-fluorouracil plus 4-epidoxorubicin in the treatment of advanced gastric carcinoma.

A total of 71 patients with advanced gastric carcinoma were randomized to receive either folinic acid + fluorouracil (arm A) or the same combination with the addition of 4-epidoxorubicin (arm B). Of the 62 evaluable patients (31 in both arms), six patients achieved a CR (10%) and 16 a PR (25.5%) with an overall response rate of 35.5% (29% in arm A and 42% in arm B; p = .28). Median duration of response was 6 and 7 months for arm A and B, respectively (p = .6). Responder patients showed a significantly better median survival duration than nonresponders (p = .01); in arm B the median survival duration was 16 months for responder patients in contrast to 7 months for nonresponders (p = .004). Toxicity was mild without significant differences between the two groups. There was one death due to hematological toxicity (arm A). The EPI-FA-FU combination appears effective and well tolerated with the additional advantage of being able to be administered in the outpatient clinic.

Laevofolinic acid, 5-fluorouracil, cyclophosphamide and escalating doses of epirubicin with granulocyte colony-stimulating factor support in locally advanced and/or metastatic breast carcinoma: a phase I-II study of the Southern Italy Oncology Group (GOIM).

Sixty-four consecutive patients with locally advanced (n = 7) or metastatic breast cancer (n = 57), were treated with a combination of laevofolinic acid 100 mg m-2 plus 5-fluorouracil 340 mg m-2 i.v. on days 1-3, cyclophosphamide 600 mg m-2 i.v. on day 1 and epirubicin 90 mg m-2 i.v. on day 1. Epirubicin dose was progressively escalated by 10 mg m-2 per cycle up to 120 mg m-2 in the absence of dose-limiting toxicities. Granulocyte colony-stimulating factor (G-CSF) was given subcutaneously in order to prevent neutropenia. Epirubicin dosage could be increased to 100 mg m-2 in 53 patients (87%), to 110 mg m-2 in 31 patients (51%) and to 120 mg m-2 in 18 cases (30%). In most patients the dose-limiting toxicity was represented by myelosuppression. A statistically significant correlation was found between median white blood count (WBC) or absolute neutrophil count (ANC) nadir and epirubicin dose level (P = 0.009; P = 0.008). Moreover, a statistically significant correlation was observed between the number of chemotherapeutic cycles, nadir ANC and WBC and the occurrence of anaemia and thrombocytopenia of increasing severity. These data suggest the occurrence of progressive cumulative bone marrow toxicity. Although patients who reached different epirubicin levels showed differences in mean dose intensity, such differences were not statistically significant. No correlation was found between the increase in dose intensity and type, rate or duration of objective responses. In patients with metastatic breast cancer the overall response rate was 72% (95% CL 66-78%) with a 25% complete response rate. Median duration of response was 10 and 13 months respectively for complete and partial responses. All patients with locally advanced breast cancer had an objective response and underwent radical mastectomy. Projected median survival of the whole series of patients with metastatic breast cancer was 20 + months. These data demonstrate that the combination of 5-fluorouracil with laevofolinic acid, cyclophosphamide and epirubicin is very active against metastatic breast cancer. Use of G-CSF allows epirubicin dosage to be increased up to 120 mg m-2 cycle-1, but its use may be linked to the occurrence of sometimes severe cumulative haematological toxicity.

Results of a clinical multicentric randomized phase-ii study of nonsmall cell lung-cancer treated with vinorelbine Cisplatin versus vinorelbine alone.

From July 1992 to December 1993, 62 patients with non-small cell lung cancer (NSCLC) were admitted to a multicentric randomized study. The patients were treated with vinorelbine (V) alone at a dose of 25 mg/m(2)/i.v. weekly or with V at a dose of 25 mg/m(2)/i.v. on day 1 and 8 plus cisplatin at a dose of 80 mg/m(2)/i.v. on day 1 every 3-4 weeks (VP). An objective response was observed in 42% of patients treated with VP versus 12.5% of those treated with vinorelbine alone (p=0.038). There was no significant difference in the median survival duration between the two groups (38 versus 30 weeks for VP and V, respectively). Toxicity was tolerable but more severe in the VP regimen. These data suggest that V is an active agent in NSCLC and that the VP regimen may yield results comparable to other cisplatin combinations for treatment of these tumors.

Biochemical modulation of fluorouracil with high dose methotrexate or folinic acid in advanced colorectal cancer patients. Gruppo Oncologico dell' Italia Meridionale (GOIM).

To compare the efficacy of two biochemical modulations of 5-Fluorouracil in advanced colorectal cancer, 104 patients were randomized to receive high dose methotrexate followed by 5-Fluorouracil and leucovorin rescue on day 1 (Arm A) or folinic acid and 5-Fluorouracil on day 1 to 5 (Arm B). Both treatments were repeated every 3 weeks. In the 92 evaluable patients, objective responses were observed in 34% in Arm A and 31% in Arm B, with a median duration of 7.5 and 8.5 months, respectively. Median overall survival was similar in both groups (12 versus 13 months, respectively). A statistically significant difference was found only between responders and non responders of group B (p = 0.004). Toxicity was mild. In conclusion, no difference in therapeutic activity was seen between the two treatments and additional biochemical modulation must be evaluated.

Sequential treatment with high-dose methotrexate and fluorouracil in advanced colorectal cancer. Experience of the Southern Italian Oncology Group (GOIM).

A total of 101 patients with advanced colorectal cancer in two consecutive Southern Italian Oncology Groups (GOIM) studies (8501 and 8801--arm A) were treated with a sequential combination of high dose methotrexate (HDMTX) and fluorouracil (FU). Of the 92 eligible patients, 2 achieved complete response (2%) and 27 partial response (30%), with a median duration of 7 months. When classified according to the time interval between administration of the two drugs, retrospective analysis showed significant improvement (p = 0.04) in overall survival in the shorter time interval group (6 hours). The observed toxicities were generally mild and transient. Our data confirm the efficacy of the synergism between the two chemotherapeutic agents, in particular when administered with a 6-hour interval. Further studies are necessary to establish the possibility of enhancing the efficacy of sequential treatment with the modulation of FU with high-dose folinic acid.

[Surgical treatment of complex lesions of the wrist]. / Traitement chirurgical des lésions complexes du carpe.

The authors underline the importance of the precocious surgical treatment of the complex lesions of the carpal bones, especially in case of concomitant neurological lesions. The quality of the late results depends on the careful anatomical reconstruction and on the fixation during a suitable period with the aim to obtain a satisfactory repair of the carpal ligaments.

Fatty acid and glucose incorporation into human adipose tissue in non-insulin-dependent diabetes and in insulinoma. Inverse relations with plasma triglyceride and glucose concentrations.

Decreased fatty acid and glucose incorporation into human adipose tissue (FIAT and GLIAT) are frequently found in primary hypertriglyceridemia (HTG) and might also contribute to the defective removal of lipoprotein triglyceride (TG) in non-insulin-dependent diabetes mellitus (NIDDM). To study this possible mechanism, FIAT and GLIAT were determined in needle biopsy specimens from 14 patients with newly diagnosed NIDDM and in 14 age- and weight-matched controls. A patient with insulinoma and hyperinsulinism was also studied. FIAT and GLIAT processes were markedly reduced in patients with NIDDM that developed at the onset of maturity. Insulinoma patients, with normal plasma TG, showed FIAT-GLIAT values in the high to normal range before operation. A direct, highly significant correlation (P less than 0.001) was demonstrated between FIAT and GLIAT in diabetics, insulinoma and controls when considered together. Plasma TG and glucose concentrations were inversely related to FIAT and GLIAT. These relationships were independent of the degree of obesity. It is suggested that impaired FIAT and GLIAT might contribute to defective TG removal and HTG which are often demonstrated in NIDDM.
