Overall survival and clinical characteristics of pancreatic cancer in BRCA mutation carriers.

BACKGROUND: The BRCA1/2 proteins are involved in regulation of cellular proliferation by DNA damage repair via homologous recombination. Therefore, BRCA1/2 mutation carriers with pancreatic cancer may have distinct biologic outcomes. METHODS: Patients with BRCA1/2-associated pancreatic ductal adenocarcinoma (PDAC) diagnosed between January 1994 and December 2012 were identified from databases at three participating institutions. Clinical data were collected. Disease-free survival and overall survival (OS) were analysed. RESULTS: Overall, 71 patients with PDAC and BRCA1 (n=21), BRCA2 (n=49) or both (n=1) mutations were identified. Mean age at diagnosis was 60.3 years (range 33-83), 81.7% (n=58) had any family history of malignancy; 30% (n=21) underwent primary resection. Out of 71 participants, 12 received experimental therapy; one patient had missing data, these 13 cases were excluded from OS analysis. Median OS for 58 patients was 14 months (95% CI 10-23 months). Median OS for patients with stage 1/2 disease has not been reached with 52% still alive at 60 months. Median OS for stage 3/4 was 12 months (95% CI 6-15). Superior OS was observed for patients with stage 3/4 treated with platinum vs those treated with non-platinum chemotherapies (22 vs 9 months; P=0.039). CONCLUSION: Superior OS was observed for advanced-disease BRCA-associated PDAC with platinum exposure.

Curcumin as an anti-cancer agent: review of the gap between basic and clinical applications.

Curcumin, commonly called diferuloyl methane, is a hydrophobic polyphenol derived from rhizome (turmeric) of the herb Curcuma longa. Extensive research over the last half century has revealed important functions of curcumin. In vitro and in vivo research has shown various activities, such as anti-inflammatory, cytokines release, antioxidant, immunomodulatory, enhancing of the apoptotic process, and anti-angiogenic properties. Curcumin has also been shown to be a mediator of chemo-resistance and radio-resistance. The anti-cancer effect has been seen in a few clinical trials, mainly as a native chemoprevention agent in colon and pancreatic cancer, cervical neoplasia and Barrets metaplasia. Some clinical studies with healthy volunteers revealed a low bioavailability of curcumin, casting doubt on the use of curcumin only as food additive. Our clinical experience with curcumin, along with the anti-metabolite gemcitabine in the treatment of patients with advanced pancreatic carcinoma, produced an objective response in less than 10% of patients, with a minor effect on survival. However, the safety of this combination was proved. Curcumin's potent anti-proliferative activity interacting with several intracellular signal transduction pathways may potentiate the anti-tumor effect of gemcitabine. The preclinical data lead to various, but still scarce, clinical studies (some on-going) that demonstrated the possible efficacy of this treatment as a chemopreventive or chemotherapeutic agent. This review will focus on the clinical evidence, including our experience with curcumin as a chemopreventive and therapeutic agent and the in vitro background results.

Pleomorphic CD8+ small/medium size cutaneous T-cell lymphoma.

Pleomorphic small/medium-sized cutaneous T-cell lymphoma is a recently recognized rare type of cutaneous T-cell lymphoma which is clinicopathologically different from mycosis fungoides and Sezary syndrome. By definition the phenotype of the neoplastic lymphocytes in pleomorphic small/medium-sized cutaneous CD3CD4CD8 but CD8 pleomorphic small/medium sized cutaneous T-cell lymphoma cases have been occasionally described. We describe a 55-year-old female with a pruritic erythematous nodule on the lateral aspect of her right foot present for 1.5 years. Histology revealed a nonepidermotropic lichenoid infiltrate in the papillary dermis and a patchy infiltrate in the mid and lower dermis composed of small to medium-sized pleomorphic lymphocytes. The immunophenotype of these lymphocytes was CD3CD4CD8TIA-1. Staining for CD20, CD30, CD56, TdT, and LMP1 were negative, and the Ki-67 proliferation index was 5% to 10%. Gene rearrangement studies demonstrated a T-cell clone. The laboratory and imaging workup did not reveal extracutaneous involvement. The lesion was treated by local irradiation but a follow-up biopsy demonstrated only partial remission. Consequently, the lesion was treated by surgical excision.

Primary lymphoma of the liver: clinical features and outcome of 9 patients.

PURPOSE: Primary liver lymphoma (PLL) is a rare lymphoproliferative disorder of unknown etiology. The prognosis in affected patients is poor, consisting of brief remissions, rapidly developing resistance to chemotherapy, early recurrence, and short survival. Most studies related to PLL are based on case reports. The aim of this retrospective study was to review our experience with PLL. PATIENTS AND METHODS: From 1985 to 2000, 9 patients who fulfilled the diagnostic criteria for PLL were treated at our hospital. All patients underwent a thorough work-up and were staged accordingly. RESULTS: The disease occured in middle and higher-aged patients (median age 63 years). Primary presenting complaints were abdominal pain, mainly in the right upper quadrant, and hepatomegaly. Liver function tests and lactate dehydrogenase (LDH) levels were elevated. Liver imaging (computed tomography-CT) and isotopic methods (gallium scan) demonstrated liver involvement either as solitary or multiple space-occupying lesions. Pathologic examination demonstrated diffuse, large cell (DLCL), B-type lymphoma in 7/9 (78%) patients. Doxorubicin-based chemotherapy was the mainstay of treatment. Good partial or complete remission rates were achieved in 7 patients, albeit for a brief period of time. CONCLUSION: Most patients with PLL succumb to their illness, despite its being relatively chemotherapy-sensitive. The introduction of intensive chemotherapy, plus/minus radiotherapy, and/or surgery has been considered in some studies.

Primary lymphoma of bone--a retrospective study. Experience at the Northern Israel Oncology Center (1979-2000).

OBJECTIVE: This retrospective study describes our experience with the diagnosis, treatment, results and long-term follow-up of primary bone lymphoma (PBL). PATIENTS AND METHODS: Nineteen patients diagnosed with PBL were reviewed. Seven patients presented with stage I(E) disease, four with stage II(E) (regional lymphadenopathy), and eight with stage IV disease (disseminated bone involvement). Only one stage IV patient exhibited 'B' symptoms. The majority (72%) demonstrated diffuse, large cell, B-type lymphoma. All patients were treated with adriamycin-based chemotherapy and consolidation radiotherapy to the primary site (8 patients: early PBL) or the most bulky area (3 patients: stage IV PBL). RESULTS: Ten stage I(E)/II(E) patients are alive with no evidence of disease (NED) and only one died due to metastatic secondary lung cancer while with NED from his PBL. Eight stage IV patients are alive with NED. Median follow-up for all living patients: 77 months. Side effects were mild and did not necessitate delay in treatment. CONCLUSIONS: Our departmental policy of treating PBL patients with an anthracycline-based regimen and involved field radiotherapy proved to be successful in achieving excellent long-term, disease-free survival. Phase III randomized, controlled, clinical trials will determine the true role of consolidation radiotherapy in PBL, when considering severe late side effects, including radiation-induced bone tumors.

Doxorubicin and paclitaxel versus doxorubicin and cyclophosphamide as first-line chemotherapy in metastatic breast cancer: The European Organization for Research and Treatment of Cancer 10961 Multicenter Phase III Trial.

PURPOSE: To compare the efficacy and tolerability of the combination of doxorubicin and paclitaxel (AT) with a standard doxorubicin and cyclophosphamide (AC) regimen as first-line chemotherapy for metastatic breast cancer. PATIENTS AND METHODS: Eligible patients were anthracycline-naive and had bidimensionally measurable metastatic breast cancer. Two hundred seventy-five patients were randomly assigned to be treated with AT (doxorubicin 60 mg/m(2) as an intravenous bolus plus paclitaxel 175 mg/m(2) as a 3-hour infusion) or AC (doxorubicin 60 mg/m(2) plus cyclophosphamide 600 mg/m(2)) every 3 weeks for a maximum of six cycles. A paclitaxel (200 mg/m(2)) and cyclophosphamide (750 mg/m(2)) dose escalation was planned at cycle 2 if no grade >or= 3 neutropenia occurred in cycle 1. The primary efficacy end point was progression-free survival (PFS). Secondary end points were response rate (RR), safety, overall survival (OS), and quality of life. RESULTS: A median number of six cycles were delivered in the two treatment arms. The relative dose-intensity and delivered cumulative dose of doxorubicin were lower in the AT arm. Dose escalation was only possible in 17% and 20% of the AT and AC patients, respectively. Median PFS was 6 months in the two treatments arms. RR was 58% versus 54%, and median OS was 20.6 versus 20.5 months in the AT and AC arms, respectively. The AT regimen was characterized by a higher incidence of febrile neutropenia, 32% versus 9% in the AC arm. CONCLUSION: No differences in the efficacy study end points were observed between the two treatment arms. Treatment-related toxicity compromised doxorubicin-delivered dose-intensity in the paclitaxel-based regimen

Fertility after treatment for Hodgkin's disease.

BACKGROUND: The investigational endeavors of ovarian cryopreservation await the clinical experience of auto- or xenotransplantation, in vitro maturation of thawed primordial follicles, their in vitro fertilization and embryo transfer. Although promising, this experience is not yet available. Moreover, the risk of possible reimplantation of malignant stem cells with the thawed cryoperserved ovary has been raised following experimental animal observations. Therefore, until these innovative endeavors prove successful, we have attempted to minimize the gonadotoxic effect of chemotherapy by the co-treatment with a gonadotropin-releasing hormone agonistic analog (GnRH-a) to induce a temporary prepubertal milieu. The immunoreactive inhibin-A and -B in these patients was measured before, during and following the gonadotoxic chemotherapy. METHODS: A prospective clinical protocol was undertaken in 60 women aged 15-40 years with lymphoma, 10 with leukemia and 10 undergoing chemotherapeutic treatments for non-malignant diseases such as systemic lupus erythematosus or other autoimmune diseases. A monthly injection of depot D-TRP(6)-GnRH-a was administered from before starting the chemotherapy until its conclusion, up to a maximum of 6 months. Hormonal profile [follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2, T, P4, insulin-like growth factor (IGF)-1, IGF-BP3 and prolactin) was taken before starting the GnRH-a/chemotherapy co-treatment, and monthly thereafter until resumtion of spontaneous ovulation. This group was compared with a control group of 60 women who have been treated with similar chemotherapy. RESULTS: Whereas all but three (40, 36 and 34 year old) of the surviving patients within the GnRH-a/ chemotherapy co-treatment group resumed spontaneous ovulation and menses within 12 months, less than half of the patients in the 'control' group (chemotherapy without GnRH-a co-treatment) resumed ovarian function and regular cyclic activity (P <0.05). The remaining 55% experienced premature ovarian failure (POF). Temporarily increased FSH concentrations were experienced by about one-third of the patients resuming cyclic ovarian function, suggesting reversible ovarian damage in a larger proportion of women than those experiencing POF. Inhibin-A and -B decreased during the GnRH-a/ chemotherapy co-treatment but increased to normal levels in patients who resumed regular ovarian cyclicity, and/or spontaneously conceived, as compared with low levels in those who developed POF. CONCLUSIONS: If these preliminary data are consisent in a larger group of patients, GnRH-a co-treatment should be considered in every woman of reproductive age receiving chemotherapy, in addition to assisted reproductive technologies and the investigation into ovarian cryopreservation for future in vitro maturation, autotransplantation or xenotransplantation.

Diagnosis and treatment of primary non-Hodgkin's lymphoma of the parotid gland: a retrospective study - Experience at the Northern Israel Oncology Center (1977-1999).

PURPOSE: The treatment and outcome of primary parotid gland non-Hodgkin's lymphoma (PGL) has rarely been described. This retrospective study documents the clinicopathologic features and treatment results in this relatively rare entity. PATIENTS AND METHODS: This study was conducted on 11 patients diagnosed and treated for primary PGL over a period of 22 years. RESULTS: Of the 4 male and 7 female patients, only one presented with the classic pattern of Sjögren's syndrome (SS) simultaneous with PGL, and only 4 patients demonstrated a low-grade Maltoma type. None of the patients had evidence of disease at the end of the primary treatment; 4 patients are alive and well from 6 months to 10 years after the end of treatment. Four patients relapsed and died due to therapy-resistant disease and 3 patients died of nonmalignant causes while in complete remission. CONCLUSION: The majority of patients with primary non- Hodgkin's lymphoma of the parotid gland present with early- stage disease. Accurate staging is mandatory. Low-grade, localized PGL can be treated successfully with primary radiotherapy alone. The aggressive type of PGL should be treated with combined chemoradiotherapy-based regimens.

Population pharmacokinetics and dynamics in phase II studies of the novel bioreductive alkylating cytotoxic indoloquinone EO9.

Population pharmacokinetic-dynamic analysis was prospectively integrated in the clinical phase II programme of EO9 to determine the population pharmacokinetic profile in a larger population of patients, to estimate individual patient pharmacokinetic parameters, and to investigate relationships between drug exposure and clinical outcome. A sparse sampling method was developed, which involved three sampling times, and was implemented during course 1. A Bayesian algorithm was used to estimate individual pharmacokinetic parameters, in particular total plasma clearance (CL) of EO9 and area under the curve (AUC). In total, samples were collected of 85 (65%) of the patients. Pharmacokinetic evaluation was successful in 61 (72%) of the sampled patients. CL of EO9 showed substantial variability (median 5.08 l/min; range 2.67-6.42) and was of the same magnitude as in the phase I study where full pharmacokinetic profiles were used. No significant relationships were noticed between exposure parameters and safety, but overall limited toxicity was observed. No tumor responses were documented. Prospective implementation of large-scale population pharmacokinetic-dynamic analysis is feasible and may generate important findings, in particular when tumor responses and relevant toxicity are observed.

[The chemotherapeutic treatment of advanced Hodgkin's disease].

Between 1972 and 1994, 121 adult patients with advanced Hodgkin's disease received MOPP (M) combination chemotherapy, MOPP alternating with ABVD (M-A) or MOPP and ABV hybrid (M/A). Radiation therapy was given to 1/3 of them. The median age was 35 years, 58% had stage III and 42% had stage IV disease. Failure-free survival at 10 years was 43.9%. It was 66.7%, 48.4% and 29.9% for patients treated by M/A, M-A and M, respectively. Overall survival at 10 years was 40.8%, and 78.2%, 48% and 27.7% for patients treated by M/A, M-A and M, respectively. Multivariate analysis found age (above or below 65 years) and combination chemotherapy (with or without adriamycin) to be significant prognostic factors. M/A combination was more myelotoxic, while M combination caused more second primaries. Today, 80% of patients with advanced Hodgkin's disease may be cured, with low rate of long-term toxicity.

The incidence of lymphoma in first-degree relatives of patients with Hodgkin disease and non-Hodgkin lymphoma: results and limitations of a registry-linked study.

BACKGROUND: The precise incidence of familial Hodgkin disease (HD) and non-Hodgkin lymphoma (NHL) in first-degree relatives is unknown. Through record linkage using two population-based sources, the authors estimated the risk of HD and NHL in family members of lymphoma probands. METHODS: The authors identified 8,037 first-degree relatives of 2,606 lymphoma cases (28.5% HD, 71.5% NHL) treated between 1970 and 1993 in 3 hospitals in Israel via the family file of the Population Registry. The authors linked this file with the Israel Cancer Registry, then calculated the standardized incidence ratio (SIR) by dividing the observed number of cases with the expected, adjusting for age, gender, calendar year, and continent of origin. RESULTS: The family file yielded incomplete ascertainment of relatives (for 771 probands, no relatives were identified). Twenty cases of lymphoma--6 HD and 14 NHL--were identified among relatives of lymphoma patients. The SIR for HD was 1.15 (95% confidence interval [CI]: 0.42-2.51) and for NHL 1.71 (95% CI: 0.93-2.87), considering the entire population of first-degree relatives. SIRs among siblings of lymphoma probands were 3.12 (95% CI: 1.01-7.29) for HD, 2.16 (95% CI: 0.45-6.31) for NHL, and 2.68 (95% CI: 1.15-5.27) for all lymphomas. There were 4 HD/HD, 1 NHL/NHL, and 3 NHL/HD sibling pairs. For HD/HD and NHL/NHL sibling pairs, the interval between lymphoma occurrence in proband and sibling was 1-4 years, whereas for HD/NHL pairs this ranged from 16 to 21 years. CONCLUSIONS: The risk of lymphoma among siblings of lymphoma probands was over 2.5-fold that of the general population and lower among other family members. The temporal proximity of HD/HD and NHL/NHL sibling pairs argues for environmental as well as genetic etiology. This method was hampered by incomplete data.

Aggressive non-Hodgkin lymphoma: early prediction of outcome with 67Ga scintigraphy.

PURPOSE: To evaluate use of gallium 67 scintigraphy early during chemotherapy to predict the outcome in patients with aggressive non-Hodgkin lymphoma. MATERIALS AND METHODS: Among 118 patients, 67Ga scintigraphy was performed after one cycle of chemotherapy in 51 patients, after a median of 3.5 cycles in 97 patients, and both in 30 patients. Computed tomography (CT) was performed after a median of 3.5 cycles of treatment in 87 patients. The failure-free survival was compared between patients with positive or negative 67Ga or CT scans by using the log-rank test. Multivariate analysis helped determine the relation between 67Ga scintigraphic and CT findings and the outcome. RESULTS: The differences in failure-free survival between patients with positive versus negative 67Ga scans after one cycle of treatment (P < .001) and at midtreatment (P < .001) were significant. There was no statistically significant difference in failure-free survival between patients with positive versus negative CT findings during treatment. In multivariate analysis, 67Ga scintigraphy after one cycle (P < .045) and at midtreatment (P < .006) was an independent factor associated with outcome. CONCLUSION: Gallium 67 scintigraphic findings after one cycle of chemotherapy and at midtreatment are predictive of outcome in patients with aggressive non-Hodgkin lymphoma. CT findings are not predictive. Early 67Ga scintigraphy during chemotherapy is a good indicator of patients who may benefit from a change to a more aggressive treatment. A future study is necessary to investigate the potential effect of early change of treatment.

Hodgkin disease: prediction of outcome with 67Ga scintigraphy after one cycle of chemotherapy.

PURPOSE: To investigate gallium 67 scintigraphy performed early during treatment as a means to predict outcome and thus to optimize treatment of Hodgkin disease (HD) in the future. MATERIALS AND METHODS: Ninety-eight patients with HD were examined. Thirty-one patients underwent 67Ga scintigraphy after one chemotherapy cycle and 83 patients after a mean 3.5 cycles (range, 2-5 cycles). Sixteen patients underwent 67Ga scintigraphy both after one cycle and at midtreatment. Patients underwent whole-body scintigraphy and single photon emission computed tomography of the torso. Torso computed tomography (CT) was performed after a mean 3.5 cycles (range, 2-6 cycles). Failure-free survival was compared between patients with positive and patients with negative test findings (Kaplan-Meier method), and the significance of the difference was calculated. The association of failure-free survival with various prognostic clinical factors before treatment was compared (log-rank test univariate analysis). RESULTS: Failure-free survival differed significantly (P < .002) between patients with positive and patients with negative 67Ga scintigrams after one chemotherapy cycle but not at midtreatment. Failure-free survival was not significantly different between patients with positive and patients with negative CT scans at midtreatment. Twenty-two (92%) of 24 patients with negative 67Ga scintigrams after one cycle and 64 (82%) of 78 patients with negative scintigrams at midtreatment remained in complete response. In four (57%) of seven patients with positive 67Ga scintigrams after one cycle, treatment failed. CONCLUSION: 67Ga scintigraphy after one cycle of chemotherapy is a good early predictor of outcome of HD.

Dexamethasone, cytarabine, ifosfamide, and cisplatin as salvage therapy in non-Hodgkin lymphoma.

The authors conducted a phase II study to evaluate a new combination of chemotherapeutic drugs that includes dexamethasone, cytarabine, ifosfamide, and cisplatin as salvage therapy in non-Hodgkin lymphoma after prior exposure to both adriamycin and etoposide. All drugs were administered intravenously over 4 consecutive days. The daily dose of dexamethasone was 20 mg twice daily. The maximal daily doses of cytarabine, ifosfamide, and cisplatin were 75 mg/m2, 1,200 mg/m2, and 20 mg/m2, respectively. Cycles were repeated every 3 weeks. A total of 31 patients were entered in the trial. Thirty patients were evaluable for response. A complete response was seen in 11 patients (37%), and a partial response was noted in six patients (20%). A significantly higher complete response rate was seen in patients with relapsing non-Hodgkin lymphoma compared with those who failed to achieve a complete response with the last chemotherapy (10/14 vs. 1/16; p < 0.013). A complete response continues in two patients who received consolidation with high-dose chemotherapy for more than 49 months and more than 60 months for each patient. Median time to treatment failure and median survival were 3.3 months and 7.5 months, respectively, for the entire group and 11 months and 30 months, respectively, for complete responders. Myelosuppression was pronounced but was usually of short duration. Neutropenic fever developed in 13 patients (42%) and in 15 of 96 cycles (16%). Platelet transfusions were required in seven patients (23%). There was one drug-related death associated with myelotoxicity. Nonhematologic toxicity was not dose limiting. The authors conclude that dexamethasone, cytarabine, ifosfamide, and cisplatin is active and a relatively tolerable regime for patients with non-Hodgkin lymphoma previously treated with adriamycin and etoposide.

Haptoglobin-related protein as a serum marker in malignant lymphoma.

A novel serum 21 kDa haptoglobin-related protein (Hpr) was investigated in patients with malignant lymphoma, to evaluate its correlation with clinical and histologic features at presentation and its possible role as a tumor marker for patient outcome. One hundred fifty eight serum samples were taken from 88 patients with non-Hodgkin's lymphoma (n=58) and Hodgkin's disease (n=30) at presentation and in the course of follow-up. Sera from 61 healthy volunteers served as normal controls. Serum Hpr levels in the lymphoma patients (median 430x10 u/ml, range 0-4000x10 ) were significantly higher than in the control group (median 68x10 u/ml, range 0-180x10 )(p=0.0001). Higher median Hpr values were detected in patients with advanced disease (p=0.013), "B" symptoms (p=0.029) and in males (p=0.053). There was also a significant correlation between Hpr and erythrocyte sedimentation rate (p=0.028). Serial determinations showed a significant decrease of the initial Hpr values obtained after treatment in 41 patients, 38 of whom achieved complete remission. In the follow-up period additional Hpr measurements were taken from 17 patients. Three of them eventually relapsed, and showed increased Hpr levels at the time of relapse. Hpr levels remained low in 11 of 14 patients who maintained complete remission, and increased in three. In conclusion, serum Hpr is a new serum tumor marker of potential use in the clinical setting of lymphoma.

Dexamethasone, etoposide, ifosfamide, and cisplatin as second-line therapy in patients with aggressive non-Hodgkin's lymphoma.

BACKGROUND: This study analyzed the long term results of a combination of dexamethasone, etoposide, ifosfamide, and cisplatin (DVIP) used at the study center as standard second-line combination therapy in patients with aggressive non-Hodgkin's lymphoma (NHL) after prior exposure to doxorubicin. METHODS: All drugs were given intravenously for 4 consecutive days. The maximum daily doses of etoposide, ifosfamide, and cisplatin were 75 mg/m2, 1200 mg/m2, and 20 mg/m2, respectively. The dexamethasone dose was 20 mg twice daily. Cycles were repeated every 3 weeks. RESULTS: Fifty-six patients were included in the study. Partial response was noted in 18 patients (32%) and complete response (CR) in 18 patients (32%). Pretreatment factors that predicted CR were CR with prior therapy (CR in 17 of 34 in patients with a recurrence vs. 1 of 21 in patients with primary refractory NHL) and age (CR in 12 of 25 patients age < or = 65 years vs. 6 of 31 patients age > 65 years). Median time to treatment failure (TTF) and median survival were 11.5 months and 30 months, respectively, for patients with a CR and 3.5 months and 8 months, respectively, for all patients. Five patients (9%) remained disease free for > 24 months. By multivariate analysis, age was the only independent prognostic factor for TTF, whereas age, serum lactate dehydrogenase, and number of extranodal sites were independent predictors for survival. Myelosuppression (median granulocyte nadir and median platelet nadir of 350/mm3 and 77,000/mm3, respectively) was the major toxicity. There was one possible drug-related death associated with myelosuppression. CONCLUSIONS: DVIP is a relatively safe salvage combination therapy in patients with aggressive NHL. Response to first-line therapy and age are the most important predictors for prognosis after the administration of DVIP. This regimen is highly active in patients with recurrent NHL, but relatively ineffective in patients with primary refractory NHL.

Phase II trial of the oral platinum complex JM216 in non-small-cell lung cancer: an EORTC early clinical studies group investigation.

BACKGROUND: JM216 is a new oral platinum complex with dose-limiting toxicity myelosuppression, now undergoing phase II evaluation. PATIENTS AND METHODS: JM216 was evaluated as first line therapy in non-small-cell lung cancer. Seventeen patients received 120 mg/m2/day for five days repeated every three weeks. RESULTS: Toxicity was manageable, the commonest side-effects being nausea, vomiting, diarrhoea, constipation and asthenia. Myelososuppression was generally grade < 2 and there were no cases of neutropenic sepsis or bleeding. Thirteen patients were fully evaluable for response. No sustained objective responses were reported. One patient was reported as stable disease had a partial response after three courses but was progressing again after four. An additional five patients had stable disease (46.2%). CONCLUSIONS: Although some patients may have had useful palliation, JM216 did not appear to have significant antitumour activity in non-small-cell lung cancer.

Benign proliferative lesions mimicking recurrence of Hodgkin's disease.

Salvage treatment in patients with recurrent Hodgkin's disease is more effective when tumor burden is minimal. That is why more intensive follow-up strategies, including frequent imaging tests, have been recently developed for the detection of early relapse. However, as screening procedures become more sensitive, there is an increasing risk of false-positive results, demonstrating nonmalignant proliferative disorders. We describe three young patients who had lymphocyte-predominant or mixed-cellularity Hodgkin's disease and were in clinical complete remission for 2.5-3 years after a combined treatment with chemotherapy and radiation. Imaging tests revealed new gallium-avid lymphadenopathy in the chest in two cases. Pathologically enlarged pelvic lymph nodes were identified in another case, after a diagnosis of recurrent disease in axilla. Those findings were interpreted as relapse, and the patients underwent thoracotomy and laparotomy, respectively, for histologic confirmation. The results showed progressively transformed germinal centers and sarcoid-like lesions, two benign proliferative disorders. When patients with Hodgkin's disease in remission show new lymphadenopathy, even with positive gallium scan, it seems mandatory to obtain tissue for histologic examination, even through invasive procedures such as laparotomy and thoracotomy, to avoid wrong diagnosis and unnecessary treatment.

EO9 phase II study in advanced breast, gastric, pancreatic and colorectal carcinoma by the EORTC Early Clinical Studies Group.

In a phase II trial, the activity of EO9, a new bioreductive alkylating agent, was assessed. EO9 was used as second-line chemotherapy in breast cancer patients and as first-line chemotherapy for patients with gastric, pancreatic and colorectal cancer. EO9 was given as a 5 min i.v. infusion at a weekly dose of 12 mg/m2. 92 patients were entered; 22 with breast cancer, 26 with colon cancer, 24 with pancreatic cancer and 20 with gastric cancer. In general, the drug was well tolerated with nausea and vomiting occurring in 26.42 and 13.3% of courses, respectively. Reversible proteinuria was the main toxicity occurring in 45% of courses. Antitumour activity was not observed. At this dose and schedule, EO9 is not an active drug in the type of tumour studied.
