Abstract
PURPOSE Rituximab has been successfully used in the treatment of B-cell non-Hodgkin's lymphoma (NHL) and some autoimmune diseases nearly for a decade. Several other malignancies and CD20-negative lymphomas have been reported in the literature after rituximab treatment. We aimed to investigate whether there is an association between rituximab treatment and the development of second malignancies. METHODS A detailed search in English language literature on reports about rituximab treatment and secondary malignancies was made through Medline. The papers were reviewed and the cases were summarized according to secondary tumor types, intervals between rituximab treatment and second malignancy occurrence, indications for rituximab treatment and cytotoxic chemotherapy administration. RESULTS There were 26 previously reported cases of CD20-negative lymphoma and solid tumors after rituximab treatment. The median age of these cases was 62 years (range 34-80). The median time period from the initiation of rituximab treatment to diagnosis of second malignancies was 5 months (range 1-40). The most frequently reported solid tumors were skin tumors (squamous cell carcinoma and Merkel cell carcinoma) (n=7; 27%), CD20-negative lymphomas (n=5; 20%), Kaposi sarcoma (n=4; 15%), and others (n=10; 38%). CONCLUSION Association between rituximab and subsequent development of second malignancies might be a coincidence. However, we suggest close monitoring for second malignancies, particularly skin tumors, in patients treated with rituximab. This issue should be evaluated in further studies.

Abstract
Testicular carcinoma is a rare tumour but the most frequently occurring form of cancer in men aged 18-35 years. In metastatic disease, following orchidectomy three or four courses of combination chemotherapy with cisplatin are given. With a general chance of cure of 80-90%, testicular cancer is still regarded as a model for a form of cancer that is curable. Due to this favourable prognosis--and to its rising incidence--the group of people who survive testicular cancer is growing and more attention is being paid to the risk of adverse consequences of treatment: secondary tumours and cardiovascular morbidity. Shared care follow-up for testicular cancer survivors with participation of both primary and secondary care is currently developed.

Abstract
To identify patients who developed secondary clonal cytogenetic aberrations (CCA) following therapy for acute promyelocytic leukemia (APL), we retrospectively analyzed cytogenetic results from 123 patients diagnosed with APL between 1995 and 2007, who had ongoing cytogenetic analysis undertaken in our laboratory. During follow-up for APL we identified 12 patients (9.8%) who developed CCA, not detected at diagnosis of APL and unrelated to their original APL karyotype. All patients had received all-trans retinoic acid (ATRA) and chemotherapy and were in complete remission for APL when secondary CCA were identified. The median latency period between diagnosis of APL and emergence of secondary CCA was 27.5 months (range: 2-54 months). To date, four patients with CCA have been diagnosed with therapy-related myelodysplastic syndrome (t-MDS)/acute myeloid leukemia (t-AML), giving a median t-MDS/AML free survival of 78 months, with follow-up ranging between 20 and 136 months from APL diagnosis. Three patients have died: two patients died of t-AML and another developed relapsed APL with persistence of his secondary clone but no diagnosis of t-MDS/AML and died from transplant-related complications. Two patients are alive with t-MDS. Seven patients with CCA are alive with no morphological evidence of MDS at the time of their last known follow-up; thus median survival has not been reached. The appearance of these abnormalities in the absence of morphological evidence of MDS in the majority of patients is unusual, and highlights the importance of continued cytogenetic follow-up in these patients.

Abstract
Recombinant interferon alpha-2b (IFN-alpha2) has direct and indirect antiproliferative effects in lymphoma, and may augment cytotoxicity when combined with chemotherapy. CALGB 8691 is a randomized study of daily oral cyclophosphamide (CPA) at 100 mg/m2 with or without IFN-alpha2 at 2 x 106 IU/m2 three times per week, followed by a second randomization between IFN-alpha2 maintenance (2 x 106 IU/m2 three times weekly) versus observation in treatment-naïve patients with follicular lymphoma (FL). Five hundred eighty-one patients were randomized to either CPA (n = 293) or CPA plus IFN-alpha2 (n = 288). One hundred five responding patients were randomized to observation and 99 to maintenance IFN-alpha2. With a median follow-up of 11.5 years, the median event-free and overall survival (OS) for CPA induction alone were 2.5 years (95% CI 2.2, 3.0) and 9 years (95% CI 7.7, 10.2), compared to 2.4 years (95% CI 2.1, 3.1) and 8.4 years (95% CI 7.5, 11.1) for the combination arm (p = NS). Patients with a partial response (PR) and randomized to observation had the worst outcome (event-free survival (EFS) 1.8 years versus 3.9 years; p = 0.002). Patients with a PR randomized to IFN-alpha2 had a similar EFS to compared to patients with complete response (CR), but this did not translate into a survival advantage. Myelosuppression was increased in IFN-alpha2-containing arms. Despite the small benefit in EFS in patients with PR randomized to IFN-alpha2 maintenance, we conclude that the addition of low dose IFN-alpha2 did not significantly improve the response rate, duration of response, event-free, or OS obtained with single-agent daily oral CPA in patients with previously untreated FL.

Abstract
OBJECTIVE Invasive breast cancer is the most common malignancy in women. Due to the declining mortality rate that is partly attributable to the use of screening mammography and effective adjuvant therapy, more women survive their breast cancers. The aim of this study was to evaluate the effects of tamoxifen on the genital tract with particular attention to the uterus and cervix. METHODS We investigated the relationship between tamoxifen and cervical or uterine cancer in Iran, reviewing all the studies performed by the Vali-Asr Gynecology Oncology Clinic in Tehran. In addition, the available data on Medline from 1980 until 2009 were reviewed. RESULTS A total of 182 articles showed associations with gynecologic malignancies. Although as many as 121 referred to links between the drug and endometrial abnormalities (polyps or cancers), 55 articles studied the relationship with changes of pap smears, four of which indicated isolated cervical metastasis followed tamoxifen use in patients with breast cancer. CONCLUSION In spite of the significant relationship between tamoxifen and endometrial cancers, cervix is rarely involved in breast cancer patients. However, vaginal bleeding or abnormal vaginal discharge has been reported in all cases before the diagnosis was made. To rule out genital tract malignancy, it is necessary, therefore, to have an annual pelvic exam, pap smear and early endometrial with endocervical curettage for tamoxifen users following a breast cancer in those with abnormal uterine bleeding or persistent vaginal discharge.

Abstract
The overall survival of patients with hairy cell leukemia (HCL) has significantly increased in recent years because of the development of effective treatments such as interferon alpha and purine analogs. Several reports have described an increased risk of secondary cancers, particularly solid tumors, in patients with HCL. We describe a case of a patient with HCL, who had prolonged pancytopenia after a single course of cladribine. Fifteen months after the diagnosis of HCL the patient developed acute myeloid leukemia (AML) and died shortly afterwards. Review of the literature shows few reports of acute leukemia in HCL patients. All of the 11 reported cases of leukemia in patients with HCL have been in patients who have been treated with either interferon alpha or purine analogs, and developed several years (mean 4.3 years; range 1.6-6.4 years) after the diagnosis of HCL. Our case is unusual in that the patient developed AML shortly (1.2 years) after the diagnosis and treatment of HCL. Further studies are needed to clarify whether leukemias seen in patients following the treatment of their HCL are incidental findings or related to HCL and its treatments.

Abstract
Acute myeloblastic leukemia cases carrying the translocation t(8;16) (p11;p13) are characterized by the M4 and M5 subtypes, erythrophagocytosis by the blast cells and a poor prognosis, suggesting a new clinical entity. The t(8;16) fuses the MOZ gene which encodes a histone acetyltransferase, located on 8p11 with the CBP gene which also encodes a histone acetyltransferase, located on 16p13, and recent reports suggested that the chimeric transcription MOZ-CBP is essential for leukemogenesis. A 68-year-old woman who had been treated mainly with paclitaxel and carboplatin for preceding ovarian cancer was admitted to our hospital, complaining of right breast mass. She was diagnosed as having breast cancer and acute monocytic leukemia (M5b). Cytogenetic study with spectral karyotyping analysis revealed the development of 47 XX, + 8, t(8;16)(p11;p13). Eleven cases of therapy-related t(8;16) leukemia including the present case have been reported, but prior treatment with paclitaxel and carboplatin-based chemotherapy has never been reported. The relation of histone acetylase and therapy-related leukemia is discussed.

Abstract
According to several reports, the 10 year incidence of secondary acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS) after systemic chemotherapy is approximately 1.5%. The cumulative risk increases by 0.25--1% for the first 8 years after treatment. We have reported only 6 cases of hematological malignancies (0.3%) after breast cancer chemotherapy in our institute. We detected 2 cases of secondary AML and 1 case of MDS, 19, 52 and 12 months, respectively, after systemic chemotherapy for breast cancer. Published data on the occurrence of secondary hematological malignancies other than AML or MDS in this setting are scarce. We encountered diffuse large B-cell lymphoma, angioimmunoblastic lymphoma and mantle cell lymphoma as secondary hematological malignancies after systemic chemotherapy for breast cancer.

Abstract
A regimen combining fludarabine, cyclophosphamide and mitoxantrone (FCM) was used to treat 29 patients with relapsed or refractory chronic lymphocytic leukemia (CLL, N = 24) and low-grade non-Hodgkin's lymphoma (NHL, N = 5) based on evidence suggesting synergism between the 3 drugs. Patients were treated with mitoxantrone 5mg/m2 i.v. day 1 only, fludarabine 25 mg/m2 i.v. for 3 days or 24 mg/m2 orally for 5 days, cyclophosphamide 250 mg/m2 i.v. for 3 days or 150 mg/m2 orally for 5 days inclusive. Eighteen patients had previously received fludarabine and most were heavily pretreated with 40% having >2 prior treatments. A median number of 4 FCM courses (range of 1-9) were given. The response rate was 78.5%: 32% complete remission, 25% nodular partial remission, 21.5%, partial remission. Median duration of response was 19 months and median survival was 42 months. Sixteen patients (57%) developed neutropenia to < 0.5 x 10(9)/l and 12 (43%) infectious complications. Four patients developed large cell lymphoma (Richter's syndrome) and 2 acute myeloid leukemia. FCM is a useful combination for relapsed or refractory CLL and low grade NHL with high response rates and long duration of response. The role of FCM as first line therapy deserves study as well as its combination with the monoclonal antibody Rituximab.

Abstract
Plasma cell leukemia (PCL) is a rare aggressive lymphoproliferative disease with a short median survival and a very poor prognosis. We report the case of a 63-year-old man who developed a PCL after 5 years of chemotherapy with hydroxyurea and busulphan for Essential thrombocythemia (ET). The karyotype showed a deletion of chromosome 7 and the plasma cells cytofluorimetric examination revealed a high expression of Multidrug Resistance related P-glycoprotein (PGP). After the second cycle of VAD chemotherapy the patient had a severe pneumonia and died with refractory PCL. This is a rare example of the coexistence of a chronic myeloproliferative and lymphoproliferative diseases in the same patient, and to the best of our knowledge, the first reported in the literature involving PCL and ET. Moreover, this case shows the possibility of secondary malignancies developing in patients treated with busulphan and hydroxyurea for chronic myeloproliferative disorders.

Abstract
The potential effects of oral contraceptive (OC) and postmenopausal hormone (PMH) use are not well understood among BRCA1 or BRCA2 (BRCA1/2) deleterious mutation carriers with a history of breast cancer. We investigated the association between OC and PMH use and risk of contralateral breast cancer (CBC) in the WECARE (Women's Environment, Cancer, and Radiation Epidemiology) Study. The WECARE Study is a population-based case-control study of 705 women with asynchronous CBC and 1,398 women with unilateral breast cancer, including 181 BRCA1/2 mutation carriers. Risk-factor information was assessed by telephone interview. Mutation status was measured using denaturing high-performance liquid chromatography followed by direct sequencing in all participants. Outcomes, treatment, and tumor characteristics were abstracted from medical records. Ever use of OCs was not associated with risk among noncarriers (RR = 0.87; 95% CI = 0.66-1.15) or BRCA2 carriers (RR = 0.82; 95% CI = 0.21-3.13). BRCA1 carriers who used OCs had a nonsignificant greater risk than nonusers (RR = 2.38; 95% CI = 0.72-7.83). Total duration of OC use and at least 5 years of use before age 30 were associated with a nonsignificant increased risk among mutation carriers but not among noncarriers. Few women had ever used PMH and we found no significant associations between lifetime use and CBC risk among carriers and noncarriers. In conclusion, the association between OC/PMH use and risk of CBC does not differ significantly between carriers and noncarriers; however, because carriers have a higher baseline risk of second primaries, even a potential small increase in risk as a result of OC use may be clinically relevant.

Abstract
Older patients are frequently excluded from randomized studies; further, it is unclear whether the morbidity associated with chemoradiotherapy with temozolomide (TMZ) outweighs the possible survival benefit in this population. TMZ administered at a dose of 150-200 mg/m2 for 5 days every 4 weeks is the standard of care in operated glioblastoma (GBM) after concurrent chemoradiotherapy. Alternative dosing regimens, such as 1-week on/1-week off, or 3-week on/1-week off, that deliver more prolonged exposure have been observed to result in higher cumulative doses than the standard 5-day regimen and may deplete tumor-derived O6-methylguanine-DNA methyltransferase (MGMT) in tumor cells, thus sensitizing tumor cells to the effects of TMZ. Currently, chemotherapy with TMZ is an interesting alternative to radiotherapy in patients with very large tumors or in the elderly who are exposed to a higher risk of delayed neurotoxicity. The DNA damage induced by nitrosoureas and TMZ is partially repaired by MGMT. Thus, administration of the combination of nitrosoureas and TMZ might overcome MGMT-mediated resistance via MGMT depletion, yielding superior treatment results compared to the administration of treatment alone. However, the results of 2 studies that administered BCNU and CCNU with TMZ reported contradictory results. The introduction of TMZ has enabled the extension of chemotherapy treatment by 1-3 years due to the improved toxicity profile and lack of cumulative toxicity. Treatment-induced myelodysplastic syndrome with or without acute myeloblastic leukemia is a well-recognized late treatment-related complication associated with TMZ administration.

Abstract
Among 1614 children with acute lymphoblastic leukemia (ALL) treated with the Nordic Society for Paediatric Haematology and Oncology (NOPHO) ALL-92 protocol, 20 patients developed a second malignant neoplasm (SMN) with a cumulative risk of 1.6% at 12 years from the diagnosis of ALL. Nine of the 16 acute myeloid leukemias or myelodysplastic syndromes had monosomy 7 (n = 7) or 7q deletions (n = 2). In Cox multivariate analysis, longer duration of oral 6-mercaptopurine (6MP)/methotrexate (MTX) maintenance therapy (P = .02; longest for standard-risk patients) and presence of high hyperdiploidy (P = .07) were related to increased risk of SMN. Thiopurine methyltransferase (TPMT) methylates 6MP and its metabolites, and thus reduces cellular levels of cytotoxic 6-thioguanine nucleotides. Of 524 patients who had erythrocyte TPMT activity measured, the median TPMT activity in 9 patients developing an SMN was significantly lower than in the 515 that did not develop an SMN (median, 12.1 vs 18.1 IU/mL; P = .02). Among 427 TPMT wild-type patients for whom the 6MP dose was registered, those who developed SMN received higher average 6MP doses than the remaining patients (69.7 vs 60.4 mg/m2; P = .03). This study indicates that the duration and intensity of 6MP/MTX maintenance therapy of childhood ALL may influence the risk of SMNs in childhood ALL.

Abstract
The treatment of pediatric malignancies represents one of the success stories of modern medicine. As survival has increased, the focus is now on minimizing harmful effects of treatment. There continue to be late toxicities and secondary malignancies of the genitourinary (GU) system for childhood cancer survivors related to the specific therapeutic exposures. A systematic approach is important for prevention and treatment of these adverse late GU effects.

Long-term outcomes to fludarabine and rituximab in Waldenström macroglobulinemia. Blood 2009; 113:3673-8.

Abstract
We report the long-term outcome of a multicenter, prospective study examining fludarabine and rituximab in Waldenström macroglobulinemia (WM). WM patients with less than 2 prior therapies were eligible. Intended therapy consisted of 6 cycles (25 mg/m(2) per day for 5 days) of fludarabine and 8 infusions (375 mg/m(2) per week) of rituximab. A total of 43 patients were enrolled. Responses were: complete response (n = 2), very good partial response (n = 14), partial response (n = 21), and minor response (n = 4), for overall and major response rates of 95.3% and 86.0%, respectively. Median time to progression for all patients was 51.2 months and was longer for untreated patients (P = .017) and those achieving at least a very good partial response (P = .049). Grade 3 or higher toxicities included neutropenia (n = 27), thrombocytopenia (n = 7), and pneumonia (n = 6), including 2 patients who died of non-Pneumocystis carinii pneumonia. With a median follow-up of 40.3 months, we observed 3 cases of transformation to aggressive lymphoma and 3 cases of myelodysplastic syndrome/acute myeloid leukemia. The results of this study demonstrate that fludarabine and rituximab are highly active in WM, although short- and long-term toxicities need to be carefully weighed against other available treatment options. This study is registered at clinicaltrials.gov as NCT00020800.

Abstract
BACKGROUND This study evaluated tumor characteristics and survival in women with breast cancer who subsequently developed uterine cancer. METHODS Information about endometrial cancer in tamoxifen users following breast cancer refered to the gynecologic oncology clinic of Vali-Asr hospital between 1997-2007 was evaluated. RESULTS Among 330 patients with endometrial cancer, 5 were in women previously diagnosed with breast cancer. Two cancers were malignant mixed Mullerian tumors of the uterus (MMMT), 2 were endometrioid adenocarcinomas, and one was a papillary clear cell carcinoma. Patients received tamoxifen for 4-8 years. The endometrial cancers occurred 2-11 years after initial treatment for the breast cancers. Four of the endometrial cancers featured abnormal uterine bleeding and one of them had increased vaginal discharge and all were diagnosed on endometrial curetting. All patients received standard surgical staging for endometrial cancer and all except one were stage I. At laparotomy of one patient, an advanced stage MMMT was found with diffused peritoneal spread and ascites. In spite of the surgery, she died of disease, 3 months later. The other patients remain recurrence-free for breast cancer and uterine cancer after 6-120 months. CONCLUSION Breast cancer patients who use tamoxifen and have early stage endometrial cancers demonstrate a good prognosis. Abnormal uterine bleeding or vaginal discharge are the most important symptoms.
