脂肪肉瘤概述

脂肪肉瘤是一種罕見且多樣化的癌症,起源於脂肪組織,約佔所有軟組織肉瘤的13-20%。它被分為四種主要的組織學亞型:良性分化脂肪肉瘤(WDLS)或非典型脂肪瘤(ALT)、去分化脂肪肉瘤(DDLS)、黏液性脂肪肉瘤(MLS)和多形性脂肪肉瘤(PLS),其中WDLS/ALT是最常見的診斷。由於其罕見性和複雜的表現,脂肪肉瘤常常被誤診——多達30%的病例可能最初被錯誤識別。這一診斷挑戰,加上有限的治療選擇,凸顯了持續研究和改善臨床方法的必要性。標準治療包括手術、放療和化療,儘管根據腫瘤亞型和疾病進展,治療效果各異。及時檢測和精確診斷對於提高生存率和治療成功率至關重要。

脂肪肉瘤可能在早期階段無聲發展,通常表現為皮膚下的無痛腫塊。主要警示信號包括新腫塊的形成、現有腫塊的持續增長、局部疼痛或麻木,以及內部出血的症狀,如大便或嘔吐中的血液。根據腫瘤的位置,症狀可能有所不同。在手臂或腿部,患者可能會注意到腫脹、疼痛、增長的腫塊和肌肉無力。當腫瘤在腹部形成時,可能會引起腹部不適、腹脹、早飽、便秘或腸道出血。隨著腫瘤增大,它可能會對附近的組織和器官施加壓力,導致不適和功能障礙。早期診斷對於更有效的管理和更好的結果至關重要。

脂肪肉瘤的確切原因尚不清楚,但据信是由脂肪細胞DNA中的遺傳突變驅動的。這些突變擾亂正常的細胞行為,導致細胞不受控制地增殖並逃避正常的細胞死亡機制。一些脂肪肉瘤保持局部並緩慢擴張,而另一些則可能侵入附近組織或通過轉移擴散到遙遠部位。儘管具體的風險因素尚未明確,但先前的輻射暴露、某些遺傳綜合徵和長期接觸有害化學物質可能會提高發展此癌症的風險。

為了確認診斷,醫生通常會進行活檢——通過針或外科手術去除一小塊組織樣本,並由病理學家在顯微鏡下檢查。如果確診為脂肪肉瘤,則會使用X光、MRI、CT掃描、超聲波或PET掃描等影像學檢查來確定腫瘤的大小和擴散情況。對活檢樣本的詳細分析有助於評估腫瘤特徵、指導治療計劃和預測結果。

治療通常以手術切除腫瘤開始,目標是消除所有癌細胞,同時保護附近結構。如果腫瘤接近或涉及關鍵器官,可能會提前使用放療或化療來縮小腫瘤,以提高手術的有效性。放射治療使用高能束針對癌細胞,可能在手術前或後進行。儘管化療對所有亞型並不有效,但在某些情況下,特別是對於侵襲性或轉移性形式,可能會建議使用,通常與其他治療結合進行。治療方案根據腫瘤類型、大小、位置和患者的整體健康狀況進行定制。

這份報告不僅提供了脂肪肉瘤藥物的最新進展,還反映出目前市場的活躍程度和未來的發展潛力。隨著對新療法的需求增加,未來幾年內,脂肪肉瘤的治療選擇有望顯著改善,這對於患者的生存率和生活質量至關重要。

Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a striking, high-resolution portrait of a young woman with long, flowing wavy brunette hair, seated gracefully on a simple black wooden chair in a dimly lit studio. She wears an oversized, off-white knitted sweater that drapes loosely over her frame, slipping off one shoulder to reveal smooth skin and add a subtle touch of sensuality. Her pose is elegant and contemplative: one arm rests gently on the chair’s backrest while her hand delicately supports her chin, and her gaze is directed thoughtfully toward the side, creating an intimate and introspective mood. The lighting is expertly crafted with a single soft, directional light source positioned to the side, casting gentle shadows that sculpt her form and highlight the texture of the knitwear and the natural contours of her legs and arms. This chiaroscuro effect enhances the depth and dimensionality of the image, emphasizing the softness of her skin and the intricate weave of the sweater. The background is a smooth, muted dark gray, providing a minimalist and distraction-free backdrop that contrasts beautifully with her light-colored apparel and warm skin tones. *** The composition is a full-body vertical frame that captures the model’s seated posture with perfect balance, positioning her slightly off-center to create visual interest and harmony. The overall color palette is subdued and warm, featuring neutral tones that evoke a sense of calm and understated elegance. The image is impeccably sharp, showcasing fine details such as the delicate waves of her hair, the subtle folds in the fabric, and the natural texture of her skin. The style is classic and timeless, blending modern minimalism with emotive portraiture to convey quiet strength, beauty, and introspection. A fierce young boy with short, curly hair stands in an action pose, reaching his hand forward as if unleashing a powerful psychic force. Bright orange energy radiates from his outstretched hand, illuminating her determined expression. he wears a patterned shirt reminiscent of 1980s fashion. Dark, monstrous creatures with elongated limbs and sharp teeth surround his, emerging from swirling smoke and fiery cracks in the environment. The entire scene glows with dramatic orange and red lightning-like streaks, creating an intense, supernatural atmosphere. Highly detailed digital painting, cinematic lighting, dynamic composition, epic fantasy-horror style, dramatic shadows, glowing embers, poster-quality artwork Create a sticker set maintaining 100% of the woman's original facial features from the provided image. Do not alter the face, focusing on ultra-realistic details of the facial structure, eyes, eyebrows, nose, mouth, and expression. The final face must be realistic, not cartoon-like. She has long, voluminous hair.
1. Makeup:Maintain Original Face: We will preserve the structure of your face, eyes, eyebrows, nose, mouth, and expression as closely as possible to the original image to maintain naturalness and uniqueness, while adjusting the tone to be softer:

Eyes: Slightly reduce the sharpness of the Cat Eye eyeliner to a thin line close to the lash line for a softer look, while still maintaining eye definition.
Eyeshadow: Use natural tones like light brown, peach, or beige.
Eyebrows: Original shape, but brushed up to look softer and more natural.
Lips: Glossy, pink-tinted, nude-pink, or coral-toned lipstick/tint to make the lips look full and moisturized. Focus on a bright but not overly intense look.
2. Hairstyle:Natural Voluminous Long Hair: Her hair is long and flowing, but the styling will emphasize natural volume and movement. Soft, natural waves.
3. Outfit:

Attire: A white open-back bodysuit paired with distressed, faded blue denim shorts. There is a message "Kunika" on the shirt.
Shoes: Elegant, simple open-toe flat sandals.
Accessories: Styled freely and fittingly for each scene.
4. Poses & Sticker Elements:Poses: Various poses such as waving, jumping, walking playfully, reading a book, holding up a sign, cheering with both hands, stretching, or making a celebratory gesture, to create a cheerful and friendly atmosphere.Decoration: Include elements like small rainbows, sparkling stars, clear bubbles, hearts, balloons, or light-colored dots to decorate and enhance the fun of each sticker scene.Style: Thin black border around the sticker. Use a modern, rounded 'Itim' style font for the text.Text: Add short emotional phrases written in a cute, beautiful script near the sticker (no speech bubbles/text boxes):

"Hello"
"Love you"
"Submitting work"
"Great"
"Got it"
"Thanks!"
"Wait a sec"
"Ready to care"
"Fight"
"Let's do it"
"So cute"
"OK"
"Sweet dreams:
"Get well soon"
"555"
"You're welcome"
"HBD" 
"OMG" 
"Sorry"
"Got a headache" 
Guidelines: Do not include a text box. Ensure balanced composition with sufficient white space—not cluttered. Match the pose to the text.
Emphasis: Reiterate 'maintain 100% of the original face features from the provided image,' 'ultra-realistic facial detail,' and 'professional studio lighting on face (realistic face, not cartoon face).

Use Cantonese in the stickers.
