PURPOSE In 1993, a randomized intervention study among patients with malignant melanoma showed a significant decrease in psychological distress and increased coping capacity 6 months after the intervention and enhanced survival 6 years later. We applied a similar intervention with a few modifications in a randomized controlled trial among Danish patients with malignant melanoma and evaluated results on immediate and long-term effects on psychological distress and coping capacity. PATIENTS AND METHODS A total of 262 patients with primary cutaneous malignant melanoma were randomly assigned to the control or intervention group. Patients in the intervention group were offered six weekly sessions of 2 hours of psychoeducation, consisting of health education, enhancement of problem-solving skills, stress management, and psychological support. The participants were assessed at baseline before random assignment and 6 and 12 months after surgery. The analyses of the main effects of the intervention were based on analyses of covariance. RESULTS The patients in the intervention group showed significantly less fatigue, greater vigor, and lower total mood disturbance compared with the controls, and they used significantly more active-behavioral and active-cognitive coping than the patients in the control group. The improvements were only significant at first follow-up. CONCLUSION The findings of this study support the results of an earlier intervention study among patients with malignant melanoma and indicate that a psychoeducational group intervention for such patients can decrease psychological distress and enhance effective coping. However, this effect is short term and the clinical relevance is not obvious.

PURPOSE The results of a randomized, intervention study done in 1993 of psychoeducation for patients with early-stage malignant melanoma showed a beneficial effect on recurrence and survival 6 years after the intervention. In the present study, we replicated the study with 258 Danish patients with malignant melanoma. We also compared recurrence and survival among the participants in the randomized study with 137 patients who refused to participate. PATIENTS AND METHODS We randomly assigned 262 patients with primary malignant melanoma to a control or an intervention group. Patients in the intervention group were offered six weekly 2-hour sessions of psychoeducation. Participants and nonparticipants were followed up for vital status and recurrence 4 to 6 years after surgical treatment. Prognostic factors (thickness of the tumor and lymph node status), sex, and age were adjusted for in a Cox regression model (proportional hazards regression) to derive an adjusted survival rate ratio and an adjusted relapse-free survival rate ratio, with 95% CIs. RESULTS The hazard ratio was 1.30 (95% CI, 0.5 to 3.5) for survival and 0.73 (95% CI, 0.3 to 1.9) for recurrence. Being a nonparticipant increased the risk for death by more than two-fold (hazard ratio, 2.26; 95% CI, 1.0 to 5.2) over that of participants. CONCLUSION Psychoeducation did not increase survival or the recurrence-free interval among patients with malignant melanoma; however, nonparticipants had a statistically significantly greater risk for death than participants.

Doxorubicin (DR) and epirubicin (ER) produce progressive tissue necrosis when extravasation occurs. Early detection and excision of all affected tissue is important. The clinical experience with fluorescence microscopic guided detection and excision in 24 patients is evaluated. 9 patients with fluorescence negative specimens were kept under observation without excision. None developed necrosis. Wide excision was performed on 15 patients with fluorescence positive specimens. Sequelae, defined as impaired function of the affected limb at the last control examination in the out-patient clinic, were observed in 8 patients. 4 of 5 patients with extravasation in the hand and 2 of 3 with extravasation in the cubital fossa were among these. Delay, defined as time from injury to surgery, was a median of 7 h, range from 3 h to 69 days. Patients developing sequelae had a median delay of roughly 4-fold that of patients without these complications. Patients with extravasation in the cubital fossa were hospitalised for the longest period: 30 days, range 24-45 days, vs. 12 days, range 7-80 days, for those with extravasation at other sites (P < 0.03). Our conclusions are: (1) fluorescence microscopic analysis is a reliable method for the detection and delineation of extravasation of DR or ER. (2) Do not use the cubital fossa or hand for the infusion of these cytostatics. (3) Act promptly if extravasation is suspected--delay leads to sequelae.

Twenty-one patients with invasive cutaneous malignant melanoma and 19 patients with basal cell skin cancer and 29 healthy volunteers were phototested on non-UV exposed buttock skin to examine their 24 h reaction to a series of increasing doses of simulated sunlight with 25% dose increments. Skin pigmentation at the phototest sites was determined by skin reflectance before testing to assure an equal level of constitutive skin pigmentation in the 3 groups. Erythema reactions were scored visually 24 hours post-exposure and objective measurements of erythema were performed by skin reflectance and laser Doppler flowmetry. In adjacent non-irradiated skin the redness was also quantified to determine the increase in redness in irradiated skin compared to non-irradiated skin. Constitutional skin pigmentation correlated well to UV sensitivity (r = 0.75) and skin redness measured by skin reflectance technique correlated to laser Doppler flowmetry (r = 0.86). No significant differences in UV doses to barely perceptible erythema or to the higher erythema grades were found between the two skin tumour groups and the control group, and no significant differences were found in skin reflectance measured redness or in laser Doppler flowmetry of any erythema reactions between the 3 groups. The 24 h erythema reaction to sunlight can therefore not be used to distinguish patients with invasive cutaneous malignant melanoma or basal cell carcinoma from normal persons.

Background/aims: The sensitivity of human skin to UV radiation is investigated by visual grading of the resulting erythema reactions 24 h after exposure to a series of increasing UV doses. Visual erythema assessment is, however, subjective and depends on pigmentation and redness of the adjacent un‐irradiated skin and can be aided by skin reflectance spectroscopy and laser Doppler blood flow measurements. Erythema is accompanied by a raised skin temperature, and this reaction might be utilised as a simple objective measurement of UV sensitivity.

Thin malignant melanomas, i.e. tumours less than 1 mm, are generally considered to have a good prognosis. The records of 148 patients with thin invasive melanomas located to the head and neck region were reviewed. All patients were followed for the excision of the primary tumour until death, or the closing date of this study (31 December 1989). Follow-up was median 9.6 years, (range: 3 months to 26.5 years). Increasing tumour thickness led to an increasing number of recurrences. However, there was no statistically significant difference in the length of recurrence-free survival or total survival between patients with tumours less than 0.76 mm and patients with tumours measuring between 0.76 mm and 0.99 mm (P>0.08). Tumours located in the scalp, neck and ears did relapse more often than tumours located to the face (P<0.03). No difference in prognosis was found in tumours that were excised with a free margin of <2.0 cm or of > or = 2.0 cm (P>0.29). Sixteen of the patients (11%) developed recurrences, 12 of these 16 patients (75%) died of disseminated melanoma. We conclude that thin head and neck melanomas do not necessarily carry an excellent prognosis. Prognosis is not dependent upon tumour thickness when less than 1.00 mm.

Abstract Electrochemotherapy is now in routine clinical use to treat cutaneous metastases of any histology, and is listed in national and international guidelines for cutaneous metastases and primary skin cancer. Electrochemotherapy is used by dermatologists, surgeons, and oncologists, and for different degrees and manifestations of metastases to skin and primary skin tumours not amenable to surgery. This treatment utilises electric pulses to permeabilize cell membranes in tumours, thus allowing a dramatic increase of the cytotoxicity of anti-cancer agents. Response rates, often after only one treatment, are very high across all tumour types. The most frequent indications are cutaneous metastases from malignant melanoma and breast cancer. In 2006, standard operating procedures (SOPs) were written for this novel technology, greatly facilitating introduction and dissemination of the therapy. Since then considerable experience has been obtained treating a wider range of tumour histologies and increasing size of tumours which was not originally thought possible. A pan-European expert panel drawn from a range of disciplines from dermatology, general surgery, head and neck surgery, plastic surgery, and oncology met to form a consensus opinion to update the SOPs based on the experience obtained. This paper contains these updated recommendations for indications for electrochemotherapy, pre-treatment information and evaluation, treatment choices, as well as follow-up.
