Major complications of Ph-MPNs are thrombosis, bleeding, transformation to myelofibrosis and leukemia. One important concern in the course of Ph-MPNs is risk of development of secondary solid cancers (SSC). In a large cohort of Turkish Ph-MPN patients, we aimed to determine the types and frequencies of SSC, to identify risk factors for SSC including role of cytoreductive therapies and to study impact of SSC on survival in Ph-MPNs.</p></div><div><h3>Methodology</h3><p>1013 patients diagnosed with Ph-MPN from 1995 and 2022 under follow up at adult hematology sections of Istanbul Bakırköy Dr Sadi Konuk Hospital and Istanbul University Medical Faculty were included in this retrospective study.</p></div><div><h3>Results</h3><p>Of the 1013 Ph- MPN patients enrolled in our study, 65, 46 and 37 patients were diagnosed with essential thrombocythemia (ET), polycythemia vera (PV) and primary myelofibrosis (PMF), respectively. Patient clinical and laboratory characteristics are summarized in Table 1. Sixty-seven patients (6.6%) developed SSC, predominantly carcinoma (64.2%), non-melanoma skin cancer (23.9%), sarcoma (4.5%), and melanoma (3%). Median time to SSC diagnosis was 80.03 ± 60.5 months with no significant difference among Ph- MPN subtypes. Compared to patients with no diagnosis of SSC, patients with SSC were older at time of Ph- MPN diagnosis (63 vs. 54 years; p&lt;0.001) and included a higher proportion of males (p=0.025). Ph- MPN patients with SSC and without SSC showed no significant difference for complete blood count parameters, spleen size, Ph-MPN diagnosis groups, driver mutation frequencies and follow-up time. Arterial thrombosis frequency was higher in patients with SSC (37.3% vs. 25.3%; p=0.030). SSC rates were 5.7% in patients not exposed to cytoreductive treatment and 5.3%, 4% and 2.1% with exposure to ruxolitinib, anagrelide, and interferon (IFN), respectively. A trend toward lower SSC rates was noted with IFN therapy (3% vs. 97%; p=0.066). SSC incidence was significantly higher in patients exposed to hydroxyurea (HU) as first-line monotherapy compared to other treatment groups (7.8% vs. 4.6%; p=0.046). Median OS in patients with SSC and patients with no diagnosis of SSC group were 273 months and 195 months, respectively.

A CT done at that time demonstrated an osteolytic lesion in her right knee in the lateral condyle. The biopsy of the lesion was consistent with the diagnosis of follicular lymphoma with plasmocytic differentiation. Bone marrow aspiration and total body CT were normal without evidence of other tumor masses. The patient underwent radiation therapy and was in perfect condition until late 2017 when she was presented to the hematology consultation because of some subcutaneous masses on her body. PET CT scan revealed several subcutaneous masses with high FDG uptake, one in her right shoulder (3.5 × 1.8 cm), two on her right breast (6.0 × 3.4 cm and 2.1 × 1.3 cm), one on the left side of her neck (1.5 × 0.6 cm), and one on her left inguinal region (4.0 × 2.3 cm). A biopsy of the mass in her inguinal region revealed the diagnosis of follicular lymphoma with plasmacytic differentiation (CD10, CD20, CD138, and MUM1 positive). She was referred to the hematology department for further evaluation and treatment. On admission, the bone marrow aspiration and biopsy showed no malignant diseases. Due to the perfect clinical condition of the patient, we decided to go with Rituximab monotherapy. But after 4 courses no improvement was seen. So, we decided to go with RCVP therapy but still, the disease was refractory, and the PET CT showed other than the subcutaneous masses, a lytic bone lesion in her left talus. We went with 2 RCHOP therapies and 4 RCHOEP plus Bortezomib and only after that, the patient went into total remission. One year later, the masses started to grow in the same location. A second biopsy revealed high-grade follicular lymphoma. We continued with R-lenalidomide but the disease was still refractory. A third biopsy performed showed a high-grade DLBCL ABC subtype. In this condition, we started salvage therapy with 2 cycles of R-BEGEV protocol and referred the patient to a clinic abroad for autologous bone marrow transplantation.

He was admitted to the nephrology department when he started immediate dialysis. Abdominal ultrasound showed splenomegaly (180mm). Because of anemia and splenomegaly, a hematologist consultation was requested. Immune electrophoresis revealed low levels of IgG, IgM, IgA, and kappa chains (4.9 mg/l) and normal levels of lambda chains (26.3 mg/l). Lambda/kappa ratio was 5.36. The sedimentation rate was 150 mm/h, there were no osteolytic bone lesions according to standard X-rays and calcium levels were normal. Peripheral blood smear showed plasma cells up to 22 percent. Bone marrow aspiration and biopsy showed full infiltration with plasma cells with lambda expression that were CD56 negative and CD38 and CD138 positive. The diagnosis of plasma cell leukemia was made, and he was transferred to the hematology union for further therapy. We started chemotherapy with the VTD PACE protocol.

In the hemogram, Hgb: 9.7g/dL Hct: 31.2% MCV: 96 fL Platlet: 126.000 / mm3. In biochemistry, creatinine:1.83mg/dL urea:80 mg/dL Na:139 mmol/L K:4.36 mmol/L Ca:10.2mg/dL uric acid:9.4mg/dL LD:343U/L. There was no sign of adrenal insufficiency other than dehydration. The patient was started on hydration and allopurinol treatments. During follow-up, urea and creatinine levels decreased to normal limits. The patient's basal cortisol was 12.02 µg/dL and ACTH was 83.8ng/L. Low-dose (1µg) ACTH test was performed on the patient, for whom chemotherapy was planned for his primary disease, with the preliminary diagnosis of adrenal insufficiency. The patient's cortisol levels were detected as 8.23-10.35-8.93-9.75 µg/dL at 30-60-90 and 120 minutes, respectively, and hydrocortisone treatment was started with the diagnosis of adrenal insufficiency. During the follow-up of the patient, R-CHOP chemotherapy was started, and since the patient had prednisolone in the chemotherapy course, hydrocortisone was discontinued during chemotherapy and isolated prednisolone treatment was given. Central Nervous System involvement was detected in the cerebrospinal fluid during intrathecal (IT) chemotherapy (Mtx, Dexamethasone, Cytosine Arabinosine). Intrathecal therapy was initially administered 3 times a week and subsequently twice a week.
