RESUMO

Few data are known regarding the use of interim positron emission tomography (iPET) after the first two cycles (iPET2) of chemotherapy in treatment-naïve classical Hodgkin lymphoma (cHL) in routine clinical practice, and about the real-life adoption of intensification strategies for iPET positive patients. We conducted a multicenter retrospective study on cHL to investigate the use of iPET in the real-life setting, its prognostic role and outcomes of patients early shifted to intensification. Six hundreds and forty-one patients were enrolled (62% had advanced stage). iPET2 was positive in 89 patients (14%) including 8.7% and 17% early and advanced stage patients, respectively (p = 0.003). Among iPET 2 positive cases treatment was immediately modified in 19 cases; in 14 cases treatment was modified after an additional positive iPET4. Overall 56 iPET2 positive patients never received intensified therapies. Most frequently used intensified therapy was autologous stem cell transplantation followed by BEACOPP. After a median follow-up of 72 months, the 5-year progression-free survival (PFS) was 82% with iPET2 positive patients showing a worse PFS compared with iPET2 negative cases: 31% versus 85%. Focusing on advanced stage patients with a positive iPET2, the 5-year PFS was 59% for patients shifted to intensified therapy at any time point versus 61% for patients who never received intensified therapy. Our study confirmed the higher curability of naïve cHL patients in a real-world setting, and the prognostic role of iPET2 in this setting. A poor adherence to response-adapted strategy which however did not translate into a difference in patient outcomes.

RESUMO

BACKGROUND: Plantar warts are common infectious cutaneous growths causing severe physiological and psychological discomforts in patients and heaving global financial burdens. However, paucity of clear-cut guidelines for plantar warts, selecting appropriate treatments for plantar warts remains challenging. The objective of the study is to evaluate the efficacy and safety of common treatments for plantar warts. METHODS: PubMed, EMbase, and The Cochrane Library were searched from inception to March 1, 2023 for randomized controlled trials (RCTs) of plantar warts. The primary outcome (complete response) and secondary outcome (recurrence and pain) were extracted and combined using Bayesian network meta-analysis (NMA) with random-effect and fixed-effect models. RESULTS: Totally, 33 RCTs were included in the systematic review and quantitative NMA. In NMA of complete response, topical application of 1% cantharidin, 20% podophylotoxin, 30% salicylic acid (CPS), microneedles plus bleomycin (MNB), and intralesional bleomycin injection (INB) were the only three treatments significantly superior to no treatment (NT) and CPS was of the highest possibility to be the top-ranked treatment (SUCRA = 0.9363). However, traditional warts treatments, salicylic acid (SA) and cryotherapy were not superior to NT. CONCLUSIONS: The NMA has produced evidence for using CPS, MNB, and INB, which are all topical antimitotic treatments, to improve the management of plantar warts. The classic treatment modalities for plantar warts, including SA and cryotherapy, may play a less important role in the clinical practice of plantar warts.

RESUMO

BACKGROUND: Keloids are common benign skin lesions originating from a disorganized fibroproliferative collagen response; these lesions often lead to both physical and psychological problems. The optimal treatment for keloids is yet to be standardized. Intralesional injection, which is simple and nontraumatic, is one of the most commonly used treatment modalities for these lesions. In this study, we compared 5 different drugs (intralesional injections) for the treatment of keloids in terms of efficacy. METHODS: We systemically searched relevant studies on PubMed, EMBASE, and Cochrane Library. Randomized clinical trials on the safety and efficacy of triamcinolone acetonide (TAC), 5-fluorouracil (5-FU), botulinum toxin A (BTA), verapamil, and bleomycin were included in this study. RESULTS: This network meta-analysis included a total of 1114 patients from 20 randomized controlled trials. Botulinum toxin A alone and TAC plus 5-FU exhibited significantly better efficacy than did 5-FU, TAC, and verapamil. No significant difference in efficacy between BTA alone and TAC combined with 5-FU was observed. No significant differences were noted in the adverse event rate between BTA, TAC plus 5-FU, 5-FU, and TAC. Furthermore, we performed surface under the cumulative ranking curve analyses to predict the rank of each intervention (by efficacy and adverse event rate). The predicted ranking by efficacy was as follows: TAC plus 5-FU, BTA, bleomycin, TAC, 5-FU, and verapamil; the predicted ranking by adverse events was as follows: TAC, 5-FU, TAC plus 5-FU, and BTA. Funnel plot analysis revealed no publication bias. CONCLUSIONS: Botulinum toxin A and TAC plus 5-FU appear to have outstanding therapeutic efficacy for keloids. The rate of adverse events was similar among BTA, TAC, 5-FU, and TAC plus 5-FU. Nonetheless, additional reviews of rigorous, large-scale randomized controlled trials are warranted for further validation of our findings.

RESUMO

OBJECTIVE: To evaluate the safety and efficacy of bleomycin polidocanol foam (BPF) sclerotherapy for venous malformations (VMs) and analyze the associated clinical outcomes and predictors. METHODS: We retrospectively assessed BPF sclerotherapy outcomes in 138 patients with VMs. We analyzed pain levels, lesion volume reduction, and subjective perception of response. Logistic regression analysis was performed to identify potential predictors of treatment outcome. Additionally, we carefully monitored and recorded complications. RESULTS: There was a notable average reduction in lesion volume by 78.50% ± 15.71%. The pain numerical rating scale (NRS) score decreased from 4.17 ± 2.63 prior to treatment to 1.05 ± 1.54 afterward, and 70.3% of the patients experienced effective relief after a single BPF treatment. Multivariate analysis revealed that a high baseline NRS (odds ratio [OR]: 4.026) and elevated activated partial thromboplastin time (APTT, OR: 1.200) were positive predictors of pain reduction. Additionally, a high baseline NRS score (OR: 1.992) and elevated thrombocytocrit (PCT, OR: 2.543) were positive predictors of incomplete postoperative pain relief. Minor complications occurred in 31 (22.46%) patients. CONCLUSION: BPF sclerotherapy is safe and effective for VMs, resulting in significant reduction in lesion volume, improved symptoms, and minimal complications. APTT and PCT levels are important predictors of pain outcomes following BPF treatment.

RESUMO

BACKGROUND: /Objective: We aimed to evaluate whether additional intralesional bleomycin injections benefit children with proliferative infantile hemangiomas (IHs). METHODS: In this retrospective case-control study, we examined the medical records of 216 infants who were followed up for proliferative IH. Patients in group 1 were treated with propranolol orally at 2 mg/kg/day. Group 2 was treated with oral propranolol combined with intralesional bleomycin injections. RESULTS: We retrospectively reviewed 95 and 121 patients in groups 1 and 2, respectively. No significant differences were observed between both groups regarding visiting age, sex, lesion thickness, or risk site. The overall cure rates in groups 1 and 2 were 77.89% (74/95) and 84.30% (102/121), respectively. The overall distribution of the length of cure significantly differed between both groups (P = 0.035). From the survival analysis (P = 0.026), the median survival time was 198 days (95% confidence interval (CI) 174.46-221.54) for group 1 and 139 days (95% CI 114.58-163.42) for group 2. The effect of treatment modality (hazard ratio (HR) = 1.41, P = 0.031) and risk site on survival time (HR = .54, P < 0.001) was significant. CONCLUSION: No significant differences were observed in the resolution of proliferative IH; however, intralesional bleomycin injection with systemic propranolol for proliferative IH treatment may provide a more rapid resolution.

RESUMO

Systemic sclerosis (SSc) is an immune-mediated rheumatic disease that is characterized by fibrosis of the skin and internal organs and vasculopathy with poor prognosis. Dangui Huoxue Preparation (DHP) is a clinically effective traditional Chinese herbal formula for the treatment of SSc in the hospital. This study aims to investigate the therapeutic effects and underlying molecular mechanisms of DHP in the treatment of SSc. SSc mice models are induced by bleomycin (BLM). Tissues of DHP group, normal control group, and positive control drug Sanqi Tongshu Capsule (STC) group are collected for inflammation, fibrosis, and vasculopathy. Also, the human dermal fibroblasts (HDF) stimulated with TGF-ß1 are analyzed for in vitro study. The expression levels of MCP-1, IFN-γ, IL-1ß, IL-10, Fizz1, iNOS, and IL12p40, and the mRNA levels of Col1a1, Col1a2, Col3a1, and Col5a1 are significantly decreased in all DHP groups and STC group compare with those in the BLM group. The main drug of DHP inhibits the proliferation and migration of HDF, reduces Ctgf, Itgb3, Itgb5 expression, and also inhibits the Smad3 pathway. In conclusion, DHP can ameliorate SSc skin inflammation, fibrosis, and vasculopathy, possibly suppressing the TGF-ß1/Smad3 signaling pathway through extracellular and intracellular mechanisms.

RESUMO

The anti-PD-1 antibodies have been reported to show a striking effect in relapsed and refractory(R/R) classical Hodgkin lymphoma (cHL), however, there is still limited real-world data assessing the role of anti-PD-1 antibody monotherapy in early-stage cHL. In this retrospective analysis, we reported the effectiveness and safety of tislelizumab monotherapy in the first-line therapy of early-stage cHL. Twenty-three consecutive patients (10 males and 13 females) with previously untreated stage I A-II B cHL were included. At interim evaluation after 2 doses of tislelizumab monotherapy, 11 of 23 patients (47.8%) achieved complete response (CR). At the end of tislelizumab monotherapy (EOTM), objective response was observed in 22 of 23 patients (95.7%), with CR in 16 patients (69.6%). Among six patients with PR-EOTM, two patients underwent 4 cycles of ABVD chemotherapy and one patient underwent 4 cycles of tislelizumab plus AVD. One patient who developed progressive disease (PD) after 4 doses of tislelizumab subsequently underwent 4 cycles of ABVD chemotherapy. Except for four patients with CR-EOTM, consolidative radiotherapy was given to 19 patients. All patients obtained CR at the end of all treatments. With a median follow-up time of 21.3 months (range, 6.9-32.7 months), the estimated 2-year PFS rate and 2-year OS rate were 95.65% and 100%, respectively. Except for grade 3 lymphocyte count decreased, no other grade 3/4 TRAE was observed. In addition, no serious AE was reported. Our preliminary data observed that tislelizumab monotherapy was safe and highly effective in previously untreated early-stage cHL.

RESUMO

OBJECTIVES: To evaluate the efficacy and tolerance after the electrochemotherapy treatment for local therapy of cutaneous and subcutaneous metastases of head-and-neck tumors and malignant melanoma refractory to standard therapies, mainly in neck metastasis of squamous cell carcinoma. And, to evaluate the relation of this response according to the skin reaction (healing with ulcer or dry crust). METHODS: prospective pase II, observational clinical study of 56 patients with metastases of head-and-neck squamous cell carcinoma (n=13), papillary thyroid carcinoma (n=4), adenoid cystic carcinoma of parotid gland (n=1) or malignant melanoma (n=37, 5 in head). Patients were treated by electrochemotherapy (application of electrical pulses into the tumor) after the administration of a single intravenous dose of bleomycin. Kaplan-Meier curves were performed. The statistical significance was evaluated using log-rank test; p-value of less than 0.05 was considered as significant. RESULTS: Overall clinical response was observed in 47 patients (84%). Local side effects were mild in all the patients. Ten patients (76.9%) with neck metastasis of squamous cell carcinoma had some degree of response, but only in one was complete. Patients even with only partial response had a higher overall survival than patients without response (p= 0.02). Most of the patients with squamous cell carcinoma had diminution of pain and anxiety. Response rate and overall survival was higher in MM patients (86.5%) than in squamous cell cancer patients (76.9%) (p= 0.043). The healing process (dry crust/ulcer) was not associated with the overall survival (p= 0.86). CONCLUSIONS: Electrochemotherapy is associated a higher overall survival and diminution of pain and anxiety. Therefore, it is an option as palliative treatment for patients with neck metastasis of squamous cell carcinoma refractory to other therapies or even as a concomitant treatment with newer immunotherapies. The type of healing of the surgical wound could not be associated with a higher rate of response or survival. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVES: The treatment of recalcitrant keloids is challenging. Although intralesional bleomycin using conventional needle injectors (CNI) is effective, it has important drawbacks, such as the need for repetitive and painful injections. Therefore, we aimed to evaluate the effectiveness, tolerability and patient satisfaction of intralesional bleomycin with lidocaine administered with a needle-free electronically-controlled pneumatic jet-injector (EPI) in recalcitrant keloids. METHODS: This retrospective study included patients with recalcitrant keloids who had received three intralesional EPI-assisted treatments with bleomycin and lidocaine. Effectiveness was assessed using the Patient and Observer Scar Assessment Scale (POSAS) at baseline and four to six weeks after the third treatment. Additionally, treatment related pain scores numeric rating scale, adverse effects, patient satisfaction and Global Aesthetic Improvement Scale (GAIS) were assessed. RESULTS: Fifteen patients with a total of >148 recalcitrant keloids were included. The median total POSAS physician- and patient-scores were respectively 40 and 41 at baseline, and reduced with respectively 7 and 6-points at follow-up ( p < 0.001; p < 0.001). The median pain scores during EPI-assisted injections were significantly lower compared to CNI-assistant injections, (2.5 vs. 7.0, respectively ( p < 0.001)). Adverse effects were mild. Overall, patients were "satisfied" or "very satisfied" with the treatments (14/15, 93.3%). The GAIS was "very improved" in one patient, "improved" in nine patients and "unaltered" in four patients. CONCLUSIONS: EPI-assisted treatment with bleomycin and lidocaine is an effective, well tolerated, patient-friendly alternative for CNI in patients with recalcitrant keloid scars. Randomized controlled trials are warranted to confirm our findings and improve the clinical management of recalcitrant keloids.

RESUMO

PURPOSE: We aimed to assess the prognostic value of baseline tumor burden and dissemination parameters extracted from 18 F-FDG PET/CT in patients with early or advanced Hodgkin lymphoma (HL) treated with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) or escalated BEACOPP (increased bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone). PATIENTS AND METHODS: Patients aged ≥18 years with classical Hodgkin lymphoma were retrospectively included. Progression-free survival (PFS) analysis of dichotomized clinicobiological and PET/CT parameters (SUV max , TMTV, TLG, D max , and D bulk ) was performed. Optimal cutoff values for quantitative metrics were defined as the values maximizing the Youden index from receiver operating characteristic analysis. PFS rates were estimated with Kaplan-Meier curves, and the log-rank test was used to assess statistical significance. Hazard ratios were calculated using Cox proportional hazards models. RESULTS: With a median age of 32 years, 166 patients were enrolled. A total of 111 patients had ABVD or ABVD-like treatment with or without radiotherapy and 55 patients with escalated BEACOPP treatment. The median follow-up was 55 months. Only International Prognostic Score (IPS >1), TMTV >107 cm 3 , and TLG >1628 were found to be significant prognostic factors for PFS on univariate analysis. Multivariate analysis revealed that IPS and TLG were independently prognostic and, combined, identified 4 risk groups ( P < 0.001): low (low TLG and low IPS; 4-year PFS, 95%), intermediate-low (high IPS and low TLG; 4-year PFS, 79%), intermediate-high (low IPS and high TLG; 4-year PFS, 78%), and high (high TLG and high IPS; 4-year PFS, 71%). CONCLUSIONS: Combining baseline TLG with IPS could improve PFS prediction.

RESUMO

There has been a renewed effort globally in the study of older Hodgkin lymphoma (HL) patients, generating a multitude of new data. For prognostication, advancing age, comorbidities, altered functional status, Hispanic ethnicity, and lack of dose intensity (especially without anthracycline) portend inferior survival. Geriatric assessments (GA), including activities of daily living (ADL) and comorbidities, should be objectively measured in all patients. In addition, proactive multidisciplinary medical management is recommended (eg, geriatrics, cardiology, primary care), and pre-phase therapy should be considered for most patients. Treatment for fit older HL patients should be given with curative intent, including anthracyclines, and bleomycin should be minimized (or avoided). Brentuximab vedotin given sequentially before and after doxorubicin, vinblastine, dacarbazine (AVD) chemotherapy for untreated patients is tolerable and effective, and frontline checkpoint inhibitor/AVD platforms are rapidly emerging. Therapy for patients who are unfit or frail, whether due to comorbidities and/or ADL loss, is less clear and should be individualized with consideration of attenuated anthracycline-based therapy versus lower-intensity regimens with inclusion of brentuximab vedotin +/- checkpoint inhibitors. For all patients, there should be clinical vigilance with close monitoring for treatment-related toxicities, including neurotoxicity, cardiopulmonary, and infectious complications. Finally, active surveillance for "postacute" complications 1 to 10 years post therapy, especially cardiac disease, is needed for cured patients. Altogether, therapy for older HL patients should include anthracycline-based therapy in most cases, and novel targeted agents should continue to be integrated into treatment paradigms, with more research needed on how best to utilize GAs for treatment decisions.

RESUMO

OBJECTIVE: To evaluate the effectiveness of intralesional bleomycin in comparison to cryotherapy in the treatment of cutaneous warts. Methods: The randomized controlled trial was conducted at the Department of Dermatology, Jinnah Postgraduate Medical Centre, Karachi, from January to July 2021, and comprised patients of either gender aged 18-60 years who had cutaneous warts for 1-48 weeks. The subjects were divided into group A treated with 0.1% intralesional bleomycin, and group B were treated with cryotherapy through non probability consecutive sampling. Follow-up examination was done at the 2, 4 and 6 weeks. Data was analysed using SPSS 23. RESULTS: Of the 154 patients, 96(62.3%) were male and 58(37.7%) were females. The overall mean age was 33.253±6.726 years. There were 77(50%) patients in each of the two groups. The therapy after 6 weeks was found to be effective 73(94.8%). group A patients and 57(74%) group B patients (p=0.001). CONCLUSIONS: Intralesional bleomycin was found to be more successful than cryotherapy in the treatment of cutaneous warts.

RESUMO

A 23-year-old male was aware of pain around his left hip joint and visited a nearby orthopedic clinic. Swelling of the right testis was pointed out, and a testicular tumor was suspected. He was referred to the urology department of a local hospital. Blood analysis showed an increase of α-fetoprotein (AFP) (3,620 ng/ml). Computed tomographic (CT) -scan revealed a left iliac bone metastasis and morbid fracture. Right radical inguinal orchiectomy was performed. The pathological examination revealed mixed germ cell tumor (embryonic carcinoma and immature teratoma: 70%, seminoma: 30%). The diagnosis was non-seminomatous germ cell tumor, stage IIIc, and poor risk on the International Germ Cell Consensus Classification. After one cycle of a bleomycin, etoposide and cisplatinum (BEP) regimen, he was referred to our hospital. After a total of 4 cycles of BEP, AFP was normalized. Denosumab was also administered monthly. The CT-scan showed a reduction of bone metastasis and recovery of ossification. Bone biopsy did not show viable tumor cells. Because extirpation of the remaining mass would require resection of the left part of the pelvic bone with significant functional loss of the left limb, we performed close follow-up after an additional 2 courses of the etoposide and cisplatin regimen. The patient is currently alive without recurrence at 45 months after the last systemic chemotherapy.

RESUMO

Lung fibrosis (LF) is a chronic progressive, incurable, and debilitating condition of the lung, which is associated with different lung disease. Treatment options are still sparse. Nintedanib, an oral tyrosine kinase inhibitor, significantly slows the LF progression. However, there is a strong need of further research and the development of novel therapies. In this study, we used a correlative set-up that combines X-ray based lung function (XLF) with microCT and whole body plethysmography (WBP) for a comprehensive functional and structural evaluation of lung fibrosis (LF) as well as for monitoring response to orally administered Nintedanib in the mouse model of bleomycin induced LF. The decline in lung function as early as one week after intratracheal bleomycin instillation was reliably detected by XLF, revealing the lowest decay rate in the LF mice compared to healthy ones. Simultaneously performed microCT and WBP measurements corroborated XLF findings by exhibiting reduced lung volume [Formula: see text] and tidal volume [Formula: see text]. In LF mice XLF also revealed profound improvement in lung function one week after Nintedanib treatment. This positive response to Nintedanib therapy was further substantiated by microCT and WBP measurements which also showed significantly improved [Formula: see text] and [Formula: see text] in the Nintedanib treated mice. By comparing the XLF data to structural features assessing the extent of fibrosis obtained by ex-vivo high-resolution synchrotron radiation-based imaging and classical histology we demonstrate that: (1) a simple low dose x-ray measurement like XLF is sensitive enough to pick up treatment response, (2) Nintedanib treatment successfully improved lung function in a bleomycin induced LF mouse model and (3) differences between the fully restored lung function and the partially reduced fibrotic burden compared to healthy and untreated mice. The presented analysis pipeline underlines the importance of a combined functional and anatomical readout to reliably measure treatment response and could easily be adapted to other preclinical lung disease models.

RESUMO

Epidemiological evidence indicates that exposure to particulate matter is linked to the development of idiopathic pulmonary fibrosis (IPF) and increases the incidence of acute exacerbations of IPF. In addition to accelerating the rate of lung function decline, exposure to fine particulate matter (particulate matter smaller than 2.5 µm [PM2.5]) is a risk factor for increased mortality in subjects with IPF. In this article, we show that exposure to PM2.5 mediates monocyte recruitment and fibrotic progression in mice with established fibrosis. In mice with established fibrosis, bronchoalveolar lavage cells showed monocyte/macrophage heterogeneity after exposure to PM2.5. These cells had a significant inflammatory and anti-inflammatory signature. The mixed heterogeneity of cells contributed to the proinflammatory and anti-inflammatory response. Although monocyte-derived macrophages were recruited to the lung in bleomycin-injured mice treated with PM2.5, recruitment of monocytes expressing Ly6Chi to the lung promoted progression of fibrosis, reduced lung aeration on computed tomography, and impacted lung compliance. Ly6Chi monocytes isolated from PM2.5-exposed fibrotic mice showed enhanced expression of proinflammatory markers compared with fibrotic mice exposed to vehicle. Moreover, IPF bronchoalveolar lavage cells treated ex vivo with PM2.5 showed an exaggerated inflammatory response. Targeting Ly6Chi monocyte recruitment inhibited fibrotic progression in mice. Moreover, the adoptive transfer of Ly6Chi monocytes exacerbated established fibrosis. These observations suggest that enhanced recruitment of Ly6Chi monocytes with a proinflammatory phenotype mediates acute exacerbations of pulmonary fibrosis, and targeting these cells may provide a potential novel therapeutic target to protect against acute exacerbations of IPF.

RESUMO

The JSH Practical Guidelines for Hematological Malignancies, 2018 expanded edition, newly adopted brentuximab vedotin, doxorubicin, vinblastine, dacarbazine(A+AVD)protocol as a standard treatment for advanced-stage classical Hodgkin lymphoma(CHL). Therefore, this retrospective analysis compared 15 patients who received A+AVD therapy with 21 patients who received doxorubicin, bleomycin, vinblastine, dacarbazine(ABVD)therapy. All patients were newly diagnosed with CHL and received induction therapy between April 2015 and June 2022 in our hospital. All except 1 patient of the A+AVD group had advanced-stage CHL. The median age was 63(23-85)years. The estimated 2-year overall survival of the A+AVD group was better than that of the ABVD group which included 6 patients with clinical stage Ⅲ or higher CHL (100% vs 66.7%, p=0.047). In contrast, there was no significant difference in the complete response rate(53.8% vs 100%, p=0.109)between the 2 groups. The overall response rate after first-line treatment(69.2% vs 100%, p=0.255), and the estimated 2-year progression-free survival(70.1% vs 66.7%, p=0.321)between the A+AVD and the ABVD groups were similar.
