Mycosis fungoides (MF) is the most common subtype of primary cutaneous T cell lymphoma (CTCL). The erythrodermic form (T4) especially impairs health-related quality of life (HR-QoL), making patients ...often incapable of self-care. Mycosis fungoides and Sézary syndrome (SS) are immunogenic neoplasms and can be recognized by the patient's immune system. The disease is chronic and immunotherapy allows for long-term control of CTCL. The paper presents a description of 2 cases of nivolumab use in the salvage treatment of erythroderma in the course of refractory mycosis fungoides. Nivolumab was used as emergency treatment, and previously patients exhausted the available treatment options. The discussed cases confirm the effectiveness of immunotherapy in the treatment of primary cutaneous T cell lymphomas. The applied treatment achieved the effect of more than one year of response (15 months), as well as a significant benefit in terms of subjective and objective quality of life. The effect was mainly related to the condition of the skin. The use of the PD-1 checkpoint inhibitor allowed for over 12 months of control in advanced, refractory and heavily pretreated cutaneous lymphoma, and was very well tolerated. More research is needed on the use of such inhibitors in the treatment of cutaneous lymphomas.
Mantle-cell lymphoma is often refractory to treatment, especially in response to second-line therapy. Inhibition of the Bruton's tyrosine kinase with ibrutinib produced responses in two thirds of ...patients in a phase 2 study; 21% of patients had a complete response.
Mantle-cell lymphoma is a distinct subtype of non-Hodgkin's lymphoma that has an aggressive clinical course and a poor prognosis.

Although these regimens have high initial response rates, most patients eventually have a relapse and die from mantle-cell lymphoma. More effective agents are needed.
Constitutive activation of B-cell receptor signaling appears to be essential for the survival and proliferation of malignant B cells, an observation that has led to the design of inhibitors of B-cell receptor–associated kinases.

Cardiovascular diseases (CVDs) are the major cause of morbidity/mortality among breast cancer (BC) patients. Observation of the daily practice in eight experienced Polish oncology centers was ...conducted to find all possible predictors of new cases of heart failure (HF) and overall survival (OS) of metastatic BC patients treated with liposomal doxorubicin, taking into account the impact of pre-existing CVDs. HF was the cause of premature discontinuation of liposomal doxorubicin therapy in 13 (3.2%) of 402 patients. The probability of developing HF was higher in women with pre-existing CVDs (HR 4.61; 95%CI 1.38-15.38). Independent of CVDs history, a lower risk of HF was observed in those treated with a cumulative dose of liposomal doxorubicin > 300 mg/m2 (HR 0.14; 95% CI 0.04-0.54) and taxane-naive (HR 0.26; 95% CI 0.07-0.96). Multivariate analysis including the presence of pre-existing CVDs and occurrence of new HF, revealed a liposomal doxorubicin in cumulative doses of > 300 mg/m2 as a beneficial predictor for OS (HR 0.61; 95% CI 0.47-0.78) independently of subsequent chemotherapy (HR 0.72; 95% CI 0.57-0.92) or endocrine therapy (HR 0.65; 95% CI 0.49-0.87). Higher doses of liposomal doxorubicin can decrease mortality in metastatic BC without increasing the risk of HF. The clinical benefit is achieved regardless of pre-existing CVDs and subsequent anticancer therapy.
The aim of this study was to assess the safety and efficacy of extending bevacizumab therapy beyond 15 months in nonprogressive ovarian cancer.
In this multinational prospective single-arm study ...(ClinicalTrials.gov NCT01239732), eligible patients had International Federation of Gynecology and Obstetrics stage IIB to IV or grade 3 stage I to IIA ovarian cancer without clinical signs or symptoms of gastrointestinal obstruction or history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within the preceding 6 months. Prior neoadjuvant chemotherapy was permitted. After debulking surgery, patients received bevacizumab 15 (or 7.5) mg/kg every 3 weeks (q3w) with 4 to 8 cycles of paclitaxel (investigator's choice of 175 mg/m q3w or 80 mg/m weekly) plus carboplatin AUC 5 to 6 q3w. Single-agent bevacizumab was continued until progression or for up to 24 months. The primary end point was safety.
Between December 2010 and May 2012, 1021 patients from 35 countries began study treatment. Bevacizumab was administered at 15 mg/kg in 89% of patients and for more than 15 months in 53%. Median follow-up duration was 32 months (range, 1-50 months). The most common all-grade adverse events were hypertension (55% of patients), neutropenia (49%), and alopecia (43%). The most common grade 3 or higher-grade adverse events were neutropenia (27%) and hypertension (25%). Bevacizumab was discontinued because of proteinuria in 5% of patients and hypertension in 3%. Median progression-free survival (PFS) was 25.5 months (95% confidence interval, 23.7-27.6 months).
Extended bevacizumab demonstrated increased incidences of proteinuria and hypertension compared with 12 or 15 months of bevacizumab in previous trials, but these rarely led to bevacizumab discontinuation. Median PFS is the longest reported for frontline bevacizumab-containing therapy. The longer bevacizumab duration beyond 15 months in this study may improve PFS without substantially compromising safety.
The optimal salvage therapy in relapsed/refractory Hodgkin lymphoma (R/R HL) has not been defined so far. The goal of this multicenter retrospective study was to evaluate efficacy and safety of BGD ...(bendamustine, gemcitabine, dexamethasone) as a second or subsequent line of therapy in classical R/R HL. We have evaluated 92 consecutive R/R HL patients treated with BGD. Median age was 34.5 (19–82) years. Fifty-eight patients (63%) had received 2 or more lines of chemotherapy, 32 patients (34.8%) radiotherapy, and 21 patients (22.8%) an autologous hematopoietic stem cell transplantation (autoHCT). Forty-four patients (47.8%) were resistant to first line of chemotherapy. BGD therapy consisted of bendamustine 90 mg/m
2
on days 1 and 2, gemcitabine 800 mg/m
2
on days 1 and 4, dexamethasone 40 mg on days 1–4. Median number of BGD cycles was 4 (2–7). The following adverse events ≥ 3 grade were noted: neutropenia (22.8%), thrombocytopenia (20.7%), anemia (15.2%), infections (10.9%), AST/ALT increase (2.2%), and skin rush (1.1%). After BGD therapy, 51 (55.4%) patients achieved complete remission, 23 (25%)—partial response, 7 (7.6%)—stable disease, and 11 (12%) patients experienced progression disease. AutoHCT was conducted in 42 (45.7%) patients after BGD therapy, and allogeneic HCT (alloHCT) in 16 (17.4%) patients. Median progression-free survival was 21 months. BGD is a highly effective, well-tolerated salvage regimen for patients with R/R HL, providing an excellent bridge to auto- or alloHCT.
Background: This was an observational study prospectively evaluating the effectiveness and safety of aflibercept/FOLFIRI administered in second-line mCRC per the reimbursement criteria in Poland. ...Methods: Consecutive mCRC patients who progressed with first-line oxaliplatin-based chemotherapy received aflibercept (4 mg/kg IV) followed by FOLFIRI every 2 weeks until progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS); overall survival (OS) and safety were the secondary endpoints. Results: A total of 93 patients were treated at 17 Polish sites. A median of 10 cycles was administered. Over a median treatment duration of 5.3 months, median PFS and median OS were 8.4 months 95% CI, 6.9–9.9 and 27.0 months 95% CI, 23.9–30.1, respectively. There was no significant impact of primary tumor location, metastatic site, or KRAS status on PFS and OS. Main grade ≥ 3 adverse events were neutropenia (16%), hypertension (8%), diarrhea (4%), and stomatitis (4%). Conclusions: The benefits/risks of Aflibercept plus FOLFIRI administered per the Polish reimbursement criteria in second-line treatment of mCRC after failure of a prior oxaliplatin-based regimen is confirmed.
ESMO guidelines recommend interferon (IFN) and methotrexate (MTX) as first-line systemic therapies in mycosis fungoides (MF) and Sezary syndrome (SS).
A prospective, head-to-head trial comparing the ...efficacy and safety of INF-α and MTX as first-line treatment in MF/SS patients.
Forty-three patients were enrolled in the trial. The response to treatment and side effects were assessed. Study variables included mSWAT, DLQI, and VAS scores.
The response rate in stage IV including SS was significantly higher in the IFN-α group than in the MTX group (100% vs. 40%;
= 0.03, respectively). No significant differences were found in response rate in stage IIB and III between treatment groups. Patients treated with IFN-α had significantly shorter time to achieve response (TTR). Significantly fewer in the IFN-α group experienced adverse events (AE) in comparison to patients treated with MTX (81% vs. 45%;
= 0.02). There was no statistically significant difference between both groups in terms of time to progression (TTP), progression-free survival (PFS), time on treatment (ToT), and time to next treatment (TTNT). The improvement in quality of life and reduction of pruritus was comparable in both treatment groups.
The obtained data suggest that the efficacy of IFN-α as first-line treatment in advanced stage (IV) MF and SS is significantly better than MTX. IFN-α presented significantly better safety and tolerability and shorter TTR than MTX. However, the results should be interpreted with caution due to scarce study groups.
CEREBEL compared the incidence of CNS metastases as first site of relapse in patients with human epidermal growth factor receptor 2-positive metastatic breast cancer receiving lapatinib-capecitabine ...or trastuzumab-capecitabine.
Patients without baseline CNS metastases were randomly assigned (1:1) to receive lapatinib-capecitabine (lapatinib 1,250 mg per day; capecitabine 2,000 mg/m(2) per day on days 1 to 14 every 21 days) or trastuzumab-capecitabine (trastuzumab loading dose of 8 mg/kg followed by an infusion of 6 mg/kg every 3 weeks; capecitabine 2,500 mg/m(2) per day on days 1 to 14 every 21 days). The primary end point was incidence of CNS metastases as first site of relapse. Secondary end points included progression-free survival (PFS) and overall survival (OS).
The study was terminated early with 540 enrolled patients (271 received lapatinib-capecitabine, and 269 received trastuzumab-capecitabine). Incidence of CNS metastases as first site of relapse was 3% (eight of 251 patients) for lapatinib-capecitabine and 5% (12 of 250 patients) for trastuzumab-capecitabine (treatment differences, -1.6%; 95% CI, -2% to 5%; P = .360). PFS and OS were longer with trastuzumab-capecitabine versus lapatinib-capecitabine (hazard ratio HR for PFS, 1.30; 95% CI, 1.04 to 1.64; HR for OS, 1.34; 95% CI, 0.95 to 1.64). Serious adverse events were reported in 13% (34 of 269 patients) and 17% (45 of 267 patients) of patients in the lapatinib-capecitabine and trastuzumab-capecitabine arms, respectively.
CEREBEL is inconclusive for the primary end point, and no difference was detected between lapatinb-capecitabine and trastuzumab-capecitabine for the incidence of CNS metastases. A better outcome was observed with trastuzumab-capecitabine in the overall population. However, lapatinib-capecitabine efficacy may have been affected by previous exposure to a trastuzumab regimen and/or when treatment was given as first- or second-line therapy in the metastatic setting.
Despite unprecedented clinical activity in mantle cell lymphoma (MCL), primary and acquired resistance to ibrutinib is common. The outcomes and ideal management of patients who experience ibrutinib ...failure are unclear. We performed a retrospective cohort study of all patients with MCL who experienced disease progression while receiving ibrutinib across 15 international sites. Medical records were evaluated for clinical characteristics, pathological and radiological data, and therapies used pre- and postibrutinib. A total of 114 subjects met eligibility criteria. The median number of prior therapies was 3 (range, 0-10). The Mantle Cell Lymphoma International Prognostic Index (MIPI) scores at the start of ibrutinib were low, intermediate, and high in 46%, 31%, and 23% of patients, respectively. Of patients with available data prior to ibrutinib and postibrutinib, 34 of 47 and 11 of 12 had a Ki67 >30%. The median time on ibrutinib was 4.7 months (range 0.7-43.6). The median overall survival (OS) following cessation of ibrutinib was 2.9 months (95% confidence interval CI, 1.6-4.9). Of the 104 patients with data available, 73 underwent subsequent treatment an average of 0.3 months after stopping ibrutinib with a median OS of 5.8 months (95% CI, 3.7-10.4). Multivariate Cox regression analysis of MIPI before postibrutinib treatment, and subsequent treatment with bendamustine, cytarabine, or lenalidomide failed to reveal any association with OS. Poor clinical outcomes were noted in the majority of patients with primary or secondary ibrutinib resistance. We could not identify treatments that clearly improved outcomes. Future trials should focus on understanding the mechanisms of ibrutinib resistance and on treatment after ibrutinib.
•Patients with mantle cell lymphoma who progressed during treatment with ibrutinib have a poor outcome.•There are no therapies that appear to be uniquely successful in the postibrutinib setting. The postibrutinib setting is an unmet need.
