Recent studies have shown a positive correlation between tumor‐related immune response markers and the poor outcome in solid tumors. In this study, we aimed to investigate the neutrophil/lymphocyte ratio (NLR) in multiple myeloma. To the best of our knowledge, this would be the second report concerning this topic.

Aims: The prognosis of acute myeloid leukemia (AML) in elderly patients is worse due to age and comorbidities. Lately, monotherapy with hypomethylating agents like azacitidine (Aza) has been used to prolong overall survival (OS) in AML patients. Herein, we present a retrospective study investigating treatment responses and OS of Aza in combination with etoposide (Eto) and cytarabine (ARA-C) in elderly. Materials and Methods: In this study, therapies and outcomes of 37 newly diagnosed AML patients, >60 years old, and ineligible for intensive chemotherapy were investigated retrospectively. Patients were grouped according to the treatments they received as follows - Group 1: low-dose conventional therapies as hydroxyurea, low-dose ARA-C, or best supportive care (n = 11); Group 2: Aza alone (n = 6); Group 3: Aza in combination with Eto and ARA-C (Aza + Eto + ARA-C, n = 20). Results: It was found that an Aza + Eto + ARA-C combination therapy had significantly better overall response rates (P = 0.002). Combination group had significantly better OS than Group 1 (8 months vs. 1 month, P < 0.001), the difference between combination and monotherapy was not significant. The OS was also associated with age and performance status, but the difference was still statistically significant after adjustment for these factors, especially for patients with younger age and better performance. Conclusions: We concluded that combination therapy of Aza with Eto and ARA-C increases response rates, and prolong survival for this poor prognosed patient group. We believe that larger controlled studies investigating Aza combinations with other antileukemic drugs will contribute to the development of tolerable treatment protocols for elderly AML patients.

Presentation of Diffuse Large B-Cell Lymphoma Relapse as a Penile Mass.

A 51-year-old man was admitted with the appearance of swelling and ulcerations of the penis that had started 2 weeks earlier. His history revealed that he was diagnosed with stage IIIB diffuse large B-cell lymphoma (DLBCL) 7 years ago, received 6 courses of R-CHOP, and was assumed to be cured after 5 uneventful years of follow-up. Swelling at the penis increased within 2 weeks with the addition of continuous pain, superficial ulcerations, and frequent and painful urination. Physical examination revealed a diffuse and indurated swelling at the shaft of the penis with an ulcer. An enlarged left inguinal lymph node was also palpable. Magnetic resonance imaging revealed a solid lesion of 55x37 mm in size, almost completely filling the penile corpus and significantly narrowing the penile urethra, extending to the glans penis. TruCut biopsy of the penile lesion was consistent with DLBCL. He was staged as Ann Arbor IIIE with positron emission tomographycomputed tomography revealing F-18 fluorodeoxyglucose involvement in the deep cervical left inguinal lymph nodes and a solid mass in the corpus penis (Figure 1). Treatment with R-CHOP started immediately and his complaints rapidly reduced after the first course. The patient is still having chemotherapy without complications and autologous stem cell transplantation will be considered for consolidation after complete remission.

Giant chondrosarcoma of rib: surgical resection and reconstruction with titanium bar, polypropylene mesh, and muscle advancement flap

Primary malignant tumours of the chest wall are rare. Chondrosarcoma is the most common malignancy of the sternum. Chondrosarcoma derived from rib is rare. Wide resection treatment is important because it is resistant to chemotherapy and radiotherapy.

Serious skin reaction associated with imatinib in a patient with chronic myeloid leukemia.

Imatinib mesylate (STI 571) is one of the fundamental chemotherapeutic agents used in the treatment of the chronic, accelerated and blastic phases of chronic myelocytic leukemia (CML), gastrointestinal stromal tumors and Philadelphia chromosome-positive acute lymphoblastic leukemia. It selectively inhibits receptor tyrosine kinases. Its effects limit the use of this drug. We present a case with a serious skin reaction requiring the discontinuation of the drug and that developed in relation to imatinib therapy. Six months prior, a 61-year-old male patient presenting to the hematology polyclinic with complaints of weight loss and sweating was hospitalized due to high leukocyte value. As a result of the hemogram, biochemistry analyses, peripheral blood smear examination, bone marrow aspiration evaluation, cytogenetic examination using FISH and PCR that were performed, CML was diagnosed. Additionally, to exclude myelofibrosis, we examined a bone marrow biopsy. Imatinib mesylate was started at 400 mg/day orally. In the fourth month of treatment, the patient complained of itching and a skin rash. Although the drug dose was reduced (300 mg/day), his complaints gradually increased. The skin biopsy result was superficial perivascular dermatitis. Imatinib was discontinued, and the patient was started on corticosteroid. The lesions disappeared completely. A month later, the patient was restarted on imatinib mesylate. However, the lesions recurred more prominently. His itching increased. The patient was considered intolerant to imatinib mesylate, and a second-generation tyrosine kinase inhibitor, dasatinib 100 mg/day, was started orally. The follow-up and treatment continues for the patient, who has been taking dasatinib 100 mg/day for the last two months without any skin finding or complaints. Imatinib mesylate-induced skin reactions are associated with the pharmacologic effect of the drug rather than hypersensitivity to the drug. Skin reactions are frequently observed, and this side effect is dose dependent. However, the interesting aspect of our case was that despite dose reduction, skin findings gradually increased, and eventually the drug had to be discontinued.
