Conclusions Epidemiological studies have repeatedly helped identify definitive triggers for several diseases. As highlighted in this perspective report, previous studies strongly argue for the interplay between intrinsic factors and putative preventable extrinsic triggers/promoters for CTCL. Given the evidence of geographical regional clustering of CTCL patients, CTCL occurrence in unrelated family members and recent evidence implicating S. aureus in the pathogenesis/progression of CTCL, more research is needed to decipher the precise mechanism by which specific environmental exposures may be driving the pathogenesis of t...
Conclusions The major challenges in the development of adoptive cell therapy for T cell tumors, as mentioned above, remain fratricide, T cell aplasia and the potential for leukemic transduction or poor T cell function if used in the autologous setting. Approaches to overcome fratricide include the genetic modification and deletion of the T cell antigen in the case of long-term CAR-T cell persistence or regulated CAR-T expression. To ensure restoration of T cell immunity, transient CAR expression can be achieved incorporation of a CAR suicide gene, transient CAR expression using mRNA electroporation, or short-lived NK cell...
ConclusionThe reason for the association between the high serum copper levels and adverse prognosis is unknown. We hypothesized that interleukin-6 is secreted primarily by non-neoplastic cells at MF skin sites, leading to release of copper by the liver. Local production of interleukin-6 at the lesion sites might conceivably also promote neoplastic cell progression by stimulation of the STAT3 pathway. Further studies on the relationship between activated tumor-associated macrophages, serum copper levels, interleukin-6, or C-reactive protein and prognosis might be informative.

Greater than normal serum copper levels in a subset of patients with early mycosis fungoides lymphoma correlated with a worse prognosis compared with that of patients with normal copper levels. The reason for this association is unknown. We hypothesized that inflammatory cytokines such as interleukin-6 secreted by inflammatory cells in skin lesions might play a role in disease progression.

ConclusionLow-dose TSEBT with adjuvant therapy results in adequate symptom palliation, comparable to standard-dose TSEBT. Low-dose TSEBT should be considered a standard treatment option in this population.
Primary cutaneous lymphomas are a heterogeneous group of lymphoid malignancies and are the second most common group of extranodal non-Hodgkin lymphoma (NHL) following gastrointestinal lymphomas.1 NHL involving the female genitalia is unusual, posing diagnostic and therapeutic challenges.2-4 Rare cases of vulvar NHL presenting as a vulvar mass were mostly diagnosed as diffuse large B-cell lymphoma and had an aggressive course.3,5 Cases of cutaneous T-cell lymphoma (CTCL) involving the vulva have been rarely reported.

Conclusion Bath PUVA and nbUVB are both effective treatments. The use of bath PUVA resulted in significantly greater disease-free survival. Micro-Abstract Phototherapy is one of the mainstay treatments for early stages mycosis fungoides (MF). Response rates are not statistically different when utilizing either bath PUVA or nbUVB in early stage MF. However, longer remission is achieved with bath PUVA therapy.
