MYCOSIS FUNGOIDES SHEIKHA CLINICAL PRESENTATION OF MF MF often has a long natural history Median duration from onset to diagnosis may be 5 years or more Usually starts with scaly skin lesions that wax & wane over years Biopsy at this stage is usually non-diagnostic Patient may respond at this stage to topical steroid Repeated biopsy is warranted if MF is suspected and biopsy is negative

MYCOSIS FUNGOIDES SHEIKHA Dear Professor Hoppe, I am writing on behalf of a strong-willed 32 year old Iraqi Kurdish patient with the diagnosis of mycosis fungoides, involving almost 20% of her body surface area. Patient gives three years history of scaly skin lesions, not responding to topical dermatological treatment. Recent histology sections showed the diagnosis of early stage mycosis fungoides. Patient desires consultation from Stanford, specifically asking for yourself. I truly appreciate having an appointment for January 2007 with a formal letter indicating the detail of the visit and the cost associated with the treatment. After having the appointment letter from your hospital, we usually need few months to process the visa to USA. Looking forward to hearing from you. Professor Anwar Sheikha, MD, FRCP, FRCPath.
MYCOSIS FUNGOIDES SHEIKHA Dear Professor Sheikha, Thank you for your inquiry regarding possible consultation and treatment for mycosis fungoides. We would be happy to see your patient at Stanford. We have a comprehensive multi-disciplinary cutaneous lymphoma clinic that includes dermatologists (Dr. Y. Kim is the Director), radiation oncologists, medical oncologists, and dermatopathologists. Our preference is to see all new patients in this clinic before making specific recommendations for therapy. We employ a variety of topical and systemic therapies for management and one of our major treatment programs is with total skin irradiation. Considering the special circumstances for this patient, to facilitate her visit and treatment, it would probably be best while we are waiting for visa clearance, etc. to be able to review the biopsy material. It might be simplest if you request the slides and then forward them to me (R. Hoppe, Department of Radiation Oncology, Room CC-G224, 875 Blake Wilbur Drive, Stanford CA 94305). I will then obtain review from Stanford Pathology.
MYCOSIS FUNGOIDES SHEIKHA Assuming we confirm the diagnosis, we would be able to save some time once the patient arrives. It is possible we may recommend treatment other than irradiation (e.g., phototherapy or topical agents) that does not require staying at Stanford. If that is the case, the expense would probably not be greater than several hundred to a few thousand dollars, depending on other examinations (e.g., radiology, etc.) that we may recommend. If we recommend a course of total skin irradiation, the "list price" would total ~$76,000. Our clinic will be meeting in January on January 11, 25, and 26 and we could arrange an appointment for any of those dates. In addition, I have taken the liberty of contacting Barbara Ralston in our Office of Special Patient Services to facilitate these arrangements. If you have any other questions, please feel free to contact me. Sincerely, Rich Hoppe Chair, Radiation Oncology
MYCOSIS FUNGOIDES SHEIKHA TOPICAL CHEMO- THERAPY TREATMENT OF MF Effective TOPICAL NITROGEN MUSTARD“MECHLORETHAMINE" Mechanism ?? AQUEOUS SOLUTION OINTMENT 10 to 20 mg Per 100 cc = Choice of aqueous or ointment depends on convenience, preference & cost Hypersensitivity is 30% with Aqueous solution & < 5% with ointment
MYCOSIS FUNGOIDES SHEIKHA Topical N2-Mustard is applied locally or to the entire skin at least daily during the clearing phase. After few weeks treatment may be applied to the affected region. N2-Mustard may only be applied to the affected anatomical site if the disease is really limited. Treatment is continued on daily basis until the lesions are cleared (6 months+) 3 to 6 months of maintenance therapy If response is slow; increase N2-Mustard concentration or frequency of application Half will relapse after discontinuation of R/ but respond again CR rate for limited patch or plaque stage “T1” is 70% to 80% The median time to skin clearance is 6 to 8 months 20% to 25% have durable CR of > 10 years Local Radiation to Refractory local lesions
